Fix home flicker on swap-back and first load - #995
Conversation
isInitialLoad regressed to 'screen === Pages.Wallet' when the tab concept was removed (#782), so every arrival at the wallet home — including back-navigation from Swap — replayed the staggered load-in animation on top of the slide-back page transition, making the home content flash in piecemeal. Restore the original semantics: only play the stagger when home is reached from a boot page (Loading, Init*, Unlock, ...). Returning from in-app pages now renders home without the replay. Adds regression tests covering back-button and root-navigation returns from the swap page.

Ponytail pass over the flicker fix: InitPassword/InitRestore/InitSuccess only navigate to InitConnect and InAppBrowser is terminal, so none can precede the wallet home — the set keeps the five pages that can. The root-nav test re-probed the same predicate the back-button test covers.
One-line predicate fix; existing suite covers the provider.
Framer Motion clears the wrapper's transform when the enter animation lands on x: 0%, which flips containing-block state for the promoted sticky home header mid-commit and lets Chromium re-raster it at a stale scale — the one-frame giant-header flash seen when returning home from the swap screen. A permanent translateZ(0) keeps the layer state stable. Reproduced with lossless frame captures: 3/3 artifact before, 0/3 after (swap -> home); send -> home was never affected.
On passwordless boot the routing effect never navigated, so the app rendered the Init onboarding screen for a frame until Init's own effect redirected to Wallet. That transient mount flashed the onboarding logo mid-boot and latched the boot overlay's fly-up exit, defeating the fly-to-target logo handoff. Navigate Init -> Wallet from the routing effect as soon as the wallet is authenticated; Init keeps its own redirect as a safety net.
Listing `screen` as a dep re-ran `no pubkey → Init` when Restore changed the page, so the restore button appeared to do nothing. Keep the Init → Wallet boot redirect; do not retrigger on screen changes.

Framer Motion 12.34.3 buildHTMLStyles transform style source build-styles
💡 Result:
<search_synthesis>
In Framer Motion version 12.34.3, buildHTMLStyles is an internal utility function responsible for constructing the CSS style object applied to DOM elements by motion components [1][2][3]. It is part of the library's rendering engine and is primarily located within the motion-dom package (specifically under packages/motion-dom/src/render/html/utils/build-styles.ts) [2][3]. Its primary purpose is to process animated values (latestValues) and map them to their corresponding CSS style properties [3]. During this process, it performs the following key actions: 1. Identification of Transform Properties: It detects specific transform-related keys (such as x, y, scale, rotate) using a predefined list of transform props [3]. 2. Transform and Transform-Origin Construction: If transform or origin-related values are present, it invokes utility functions like buildTransform (often imported from a sister module like build-transform.ts) to generate a correctly formatted transform string [3][4]. 3. Style Assignment: It updates a provided state object (typically state.style) with non-transform values, ensuring appropriate units are applied (e.g., converting a number 0 to "0px") [3]. 4. CSS Variable Handling: It distinguishes between standard CSS properties and CSS variables (identified by prefixes like --), routing them accordingly to the style or vars objects [3]. This function effectively abstracts the complexity of reconciling individual motion values into a single, valid CSS style object that the browser can render [3]. It is considered an internal API and is subject to change without warning, as is standard for non-public-facing utilities in the motion codebase [5].

Preserve translateZ(0) on the animated page.
pageTransitionVariants supplies x, so motion-dom 12.34.3 rebuilds style.transform with buildTransform instead of composing the literal value. The animated element can therefore render translateX(...) or none without translateZ(0). Move the promotion to a non-animated wrapper or use transformTemplate to prepend it.

Cover the authenticated-wallet redirect.
The existing keeps authenticated but uninitialized wallets on loading case uses the default stored pubkey and Pages.Init, but it does not assert Pages.Wallet. Removing the redirect would not fail that test or the other App tests. Add a focused test for an authenticated wallet with a stored pubkey and assert navigation to Pages.Wallet.

Swap (and other in-app pages) returning home still felt jumpy: the whole home slid in while the action buttons replayed their load-in. Fade the outgoing page off an already-settled home, and keep the button intro on first boot only.

UI/navigation-only change — no VTXO, signing, forfeit, or round lifecycle code is touched. Danger's "protocol code needs tests" flag is a false positive here.
Correctness
BOOT_PAGES coverage is correct. The onboarding paths all terminate via InitConnect → Wallet, and InitConnect is in BOOT_PAGES, so isInitialLoad=true (and thus the stagger animation) fires correctly for new-user first-entry. Restore and Password flows route through the same last hop. ✓
isInitialLoad ref-read during render (navigation.tsx).
previousPage is a useRef, so it won't trigger its own re-render, but it is always written immediately before setScreen() in every code path (navigate, replace, handlePopState). The value is therefore always current by the time isInitialLoad is evaluated during the render that setScreen triggered. ✓
'fade' animate variant falling through to { duration: 0 } (animations.ts line 32–33).
The incoming home page starts at { opacity: 1 } (the initial fall-through) and transitions instantly — it's already beneath the fading page. The outgoing page carries zIndex: 1 during its 0.18 s fade to sit above the settled home. Sequence is sound. ✓
handlePopState — swipe vs button (navigation.tsx diff line ~237).
fromButton ? … 'fade' : 'none' means swipe-back to Wallet remains instant (existing behaviour), while button-back to Wallet fades the outgoing page. Intentional and correct. ✓
Issues
1. Missing lint suppression alongside the missing-dep comment — src/App.tsx
The new line reads screen inside the useEffect but screen is deliberately omitted from the deps array. The comment explains why, which is appreciated. However, react-hooks/exhaustive-deps will still emit a warning (or error, depending on config), and without an explicit suppression comment a future contributor may see the lint failure and "fix" it by adding screen — reintroducing the exact bounce bug this PR resolves. Add:
// eslint-disable-next-line react-hooks/exhaustive-deps -- screen intentionally omitted; see comment aboveon the deps array line. The comment + suppression together form a single coherent artefact that survives future edits.
2. navigation.test.tsx — new behaviour not covered
The existing test exercises the old isInitialLoad = screen === Pages.Wallet path (Init → Wallet, duplicate calls). With the PR's change, isInitialLoad is additionally gated on BOOT_PAGES.has(previousPage.current). The test still passes (Init is in BOOT_PAGES), but the new negative case — returning from an in-app page (WalletSwap → Wallet) should produce isInitialLoad=false — has no coverage. A regression there would silently replay the stagger on every swap-back.
Suggested addition:
it('clears the initial-load flag when navigating home from a non-boot page', async () => {
// arrange: start on Wallet, navigate to WalletSwap (simulates in-app nav)
// then navigate back to Wallet
// assert: isInitialLoad === false
})Similarly, the new 'fade' direction emitted by navigate(Pages.Wallet) from a non-boot/non-root page is untested.
3. transform: 'translateZ(0)' applied to the reduced-motion code path — src/components/PageTransition.tsx
When prefersReduced is true, the component returns <div style={style}>…</div> with the same style object, which now includes transform: 'translateZ(0)'. This permanently promotes a compositing layer for users who've opted out of animations specifically to save battery/reduce GPU work. Consider:
const style = { … } // without transform
const gpuStyle = { ...style, transform: 'translateZ(0)' }
// use gpuStyle only on the motion.div pathMinor, but worth fixing given that the workaround targets a GPU compositing bug.
4. willChange + translateZ(0) redundancy
src/components/PageTransition.tsx now has both willChange: 'transform, opacity' and transform: 'translateZ(0)' on every page wrapper. willChange: 'transform' already tells the browser to prepare a compositing layer; translateZ(0) is a legacy promotion hack that becomes redundant (though harmless) when willChange is set. No action required, just noting it.
Summary
Two actionable items before merge:
- Add the
eslint-disablesuppression at the deps array inApp.tsxso the intentional omission is self-defending. - Add at minimum one test covering
isInitialLoad=falseon in-app → Wallet navigation.
The reduced-motion compositing leak (#3) is worth a follow-up but not a blocker.
This reverts commit 21da102.

Follow-up pass — 2 new commits (adb0ac9, 21da102) since last review. 0 prior issues fixed. 3 remain open.
Prior-issue close-out
Issue 1 — Missing eslint-disable on the intentional screen dep omission (src/App.tsx) — Still open
App.tsx (routing useEffect) reads screen at the line:
if (screen === Pages.Init && authState === 'authenticated') return navigate(Pages.Wallet)and screen is deliberately absent from the deps array. The prose comment survives, but there is still no // eslint-disable-next-line react-hooks/exhaustive-deps suppression on the deps line. A future contributor hitting the lint warning could "fix" it by adding screen, reintroducing the exact bounce this PR resolves. Not changed in this increment.
Issue 2 — Navigation tests missing (isInitialLoad=false, 'fade' direction) — Still open; made slightly worse
adb0ac9 dropped the restore-bounce test without replacement. The behaviour it verified (routing effect not re-running on screen change) is still present in code at App.tsx but there is now no automated guard for it. The new 'fade' direction path and isInitialLoad=false on in-app → Wallet navigation remain uncovered. Dropping a test without a replacement is a net regression.
Issue 3 — translateZ(0) on the prefers-reduced-motion code path (src/components/PageTransition.tsx) — Still open
PageTransition.tsx was not touched in this increment. The shared style object (which includes transform: 'translateZ(0)') is still passed to the plain <div> returned when prefersReduced is true, permanently promoting a GPU compositing layer for users who opted out of animations. The fix — using a separate style object without the transform for that branch — was not applied.
Issue 4 — willChange + translateZ(0) redundancy — No change (informational; no action required as noted before)
Incremental diff assessment (adb0ac9 · 21da102)
No new concerns. The 'fade' direction implementation is correct:
animations.ts:fadeenter falls through to{ opacity: 1, duration: 0 }— Wallet is pre-rendered underneath and appears instantly.fadeexit produces{ opacity: 0, zIndex: 1, transition: { duration: 0.18 } }— the outgoing page sits above the settled home and fades off. Sequence is sound.navigation.tsx:navigate()path usesBOOT_PAGES.has(screenRef.current)to distinguish first-boot (→'none', logo overlay takes over) from in-app return (→'fade').handlePopState()path usesprevPage === Pages.Wallet ? 'fade' : 'back'for button-driven pops, leaving swipe-back as'none'. Both are correct and consistent.index.css: animation delays correctly scoped to.home-quick-actions--intro .home-quick-action. Base class no longer carries theanimationor--home-action-load-delaydeclarations.HomeQuickActions.tsx/Index.tsx:intro={shouldStagger}prop wiring is clean; class toggle is straightforward.
No protocol, security, or cross-repo issues introduced by this increment. The three open items from the prior pass remain the only outstanding work.
Home flickered in two places:
Fixed by playing the stagger only on real boot, keeping the page wrapper’s transform after the slide, and sending a ready wallet straight home.
Also: Restore (and Create) were bouncing back to onboarding because that last redirect re-ran on every screen change. They leave Init again.
