Implement proper atmospheric background pipeline:
- Random NON-CENTERED crop (150-300% zoom) to break composition
- Extreme blur at small size (destroys all semantic detail)
- Scale up with smoothing for additional blur
- Color adjustments (saturation 1.4x, brightness 0.5x)
- Vignette overlay
The background is now an unrecognizable color field derived from
artwork colors. Acceptance test: "Can I identify the album from
the background alone?" must be NO.
Applies to both WebGL and CSS fallback renderers.
- ImmersiveBackground now checks WebGL2 availability on mount
- Dynamically imports ImmersiveAmbientCanvas when WebGL2 available
- Falls back to CSS blur when WebGL2 unavailable
- New props: enableAmbient (default true), ambientIntensity
Automatic renderer selection:
1. Check BUILD_IMMERSIVE_ENABLED (compile-time)
2. Check isRuntimeEnabled() (user preference)
3. Check isWebGL2Available() (browser capability)
4. If all pass: use WebGL2 with ambient motion
5. Otherwise: use CSS fallback (original behavior)
- Increase canvas size from 8x8 to 64x64 to reduce visible pixelation
- Add small CSS blur(40px) to smooth the result
- Key: blur(40px) on 64x64 is much cheaper than blur(120px) on full image
- Adjusted brightness slightly darker (0.55x) for better text contrast
Performance problem:
- WebKitWebProcess consuming 97% CPU on one core
- Cause: CSS filter: blur(120px) on large image is extremely expensive
in WebKit/GTK which cannot GPU-accelerate this operation
Solution:
- Replace CSS blur with Canvas-based tiny thumbnail approach
- Draw image to 8x8 canvas, apply color adjustments, scale up via CSS
- Natural pixelation creates blur-like effect with ZERO CPU cost
- Remove backdrop-filter: blur() from header elements (use solid bg)
Also fixed:
- Change Mic icon to Mic2 to match rest of app
- Add missing i18n translations for player.credits and player.suggestions
Display modes:
- Coverflow: centered album art with track info
- Split: artwork + panel side by side (current default)
- Lyrics Focus: single line at a time, large centered text
- Queue Focus: full screen queue view
- Visualizer Focus: full screen visualizer
Background:
- Heavy CSS blur (120px) for abstract color blobs
- No recognizable image, just colors
Keyboard shortcuts: 1-5 to switch modes
Inspired by Cider 3's immersive player design.
Replace blur approach with full resolution artwork:
- Artwork scaled 115% to hide edges
- Strong vignette overlay fading to black at edges
- Gradient overlays for text readability (header, controls, lyrics)
- Slight desaturation for better contrast
- Simpler and more visually impactful
