What’s Changed
v1.9.1 refines the Transparent UI feature introduced in v1.9.0, with a focus on macOS performance.
On macOS, the transparent and glass-blur effect previously relied on the CSS backdrop-filter blur, which kept the GPU and compositor under continuous load and noticeably increased power usage.
This release switches macOS to native vibrancy (NSVisualEffectView), so the frosted-glass look is rendered by the system instead of being repainted every frame.
The Transparent UI setting has also been reorganized into a dedicated Experimental features section. A calmer “Experimental” badge and a short note replace the earlier warning callout, while still making clear that the feature is experimental and may increase power usage, especially on macOS.
macOS Performance
- Switched macOS Transparent UI to native vibrancy (NSVisualEffectView) instead of the CSS
backdrop-filterblur, reducing GPU and power usage. - Added a 4-step frost slider (off / low / medium / high) on macOS, mapped to native materials and reusing the existing glass blur setting.
- Rendered web UI surfaces as fully opaque on macOS so the native vibrancy effect shows through without per-frame compositing.
Transparent UI
- Moved Transparent UI into a dedicated Experimental features section.
- Replaced the warning callout with a calmer “Experimental” badge and a short note.
- Kept guidance that the feature is experimental and may increase power usage, especially on macOS.
