Root cause: 225 individually animated DOM elements forced Chrome's
compositor to create separate paint regions per element. Any hover
state change on page content triggered re-compositing of all 225
regions, causing visible flickering on all pages.
Canvas fix: single <canvas> element renders the entire grid effect
via requestAnimationFrame. Canvas content is pixel-based and cannot
be affected by DOM hover state changes on other elements.
Additional fixes:
- Fix z-index collision: portal z-index -1 → -2 (was same as body::before noise)
- Replace all transition-all with specific properties on .btn, .btn-icon,
.input, .nav-item, .bottom-nav-item, checkbox
- Remove backdrop-blur-sm from desktop .bento-card and .card
(forced Chrome to re-sample animated background pixels on every hover)
Remove translateZ(0) from base states of .bento-card, .card, .glass
and their light theme variants. Remove transform-gpu from Card.tsx.
Change bentoFadeIn animation to end with transform:none instead of
translateY(0). GPU promotion now only occurs during hover/active
interactions, preventing Chrome from creating excessive compositing
layers that cause flickering with animated backgrounds.
The boxes background was creating 225 motion.div elements, each running
independent opacity animations via framer-motion JS on the main thread.
This blocked hover transitions on cards, causing visible flickering.
CSS @keyframes run on the compositor thread and have zero main-thread
cost, eliminating the interference with user interactions.
Previous isolation:isolate fix didn't work because:
- position:fixed elements still see through isolation boundary
- backdrop-filter samples all rendered content regardless of stacking context
- The real issue: animated background at z-index:0 with will-change:transform
forces Chrome to implicitly composite EVERY overlapping element
Fix: render BackgroundRenderer via createPortal on document.body with
z-index:-1, placing it below the root stacking context. This eliminates
implicit compositing entirely.
Also:
- Remove backdrop-blur-xl from desktop header (was resampling bg 60fps)
- Remove will-change:opacity from card ::after pseudo-element
- Replace transition-all with transition-colors on header buttons
Root cause: backdrop-filter on header/nav resamples the animated
background 60fps, causing GPU compositing flicker (Chromium bug).
- Add isolation: isolate wrapper in AppShell to prevent backdrop-filter
from seeing through to the animated background layer
- Add will-change: transform + translateZ(0) to BackgroundRenderer
for stable GPU layer
- Replace contain: layout style with contain: content on main
- Replace transition-all with specific properties in Card component
- Preserve translateZ(0) on all hover/active transforms to prevent
GPU compositing layer teardown/recreation cycle
- Lower body::before noise texture z-index to -1
- Add will-change: opacity to card spotlight pseudo-element
- Include backdrop-blur-linear in mobile performance override
- Replace transition-all with specific properties in BentoCard
- Extract CountdownTimer into React.memo component to isolate 1s
interval re-renders from the full Subscription page
- Add box-shadow transition to .hover-border-gradient (was instant)
- Remove conflicting p-[1.5px] from PurchaseCTAButton (CSS border
already handles 1.5px)
- Replace transition-all with specific properties on bento-card-hover,
bento-card-glow, device dots, toggle switches, progress bars
- Reduce translateY hover from -4px to -2px to prevent cursor
losing hover target during fast vertical mouse movement

Remove opacity from beamDash keyframes — opacity on SVG paths triggers
full-page repaints. Animate only stroke-dashoffset (compositor-friendly).
Reduce animated paths from 50 to 17 (every 3rd). Isolate container with
contain:strict + will-change:transform for own compositor layer.
ThemeTab: throttle applyThemeColors via requestAnimationFrame (1x/frame),
debounce queryClient.setQueryData 150ms. Fixes browser lag when dragging
color sliders (~60 calls/sec × 50+ CSS var writes).
BackgroundBeams: replace 20 framer-motion linearGradient JS loops with
pure CSS stroke-dashoffset animation on all 50 original Aceternity paths.
Single shared gradient, GPU-composited keyframes, zero per-frame JS.
