Description

Describe the bug

In cargo tauri dev, scrollable elements seem to behave 'normally'. So too in running target/release/appname directly.

In running target/release/bundle/appimage/appnameversionetc however, it seems to have a strange laggy/inertia-ridden behaviour, whereby it's very slow while scrolling, but then jumps when I stop.

Reproduction

  1. Create some scrollable view
  2. cargo tauri build --release
  3. Test target/release/app and target/release/bundle/appimage/appversionetc. and observe difference in scroll

Expected behavior

Same non-laggy scroll behaviour in the appimage.

Research direction
The issue reports laggy/inertia scrolling specifically in the AppImage build, while the binary works normally. Likely due to differences in webview environment or GPU acceleration in the AppImage sandbox. Investigate tauri apps/wry#268 for similar issues. Check the AppImage build configuration, particularly webview flags, and test with different webview backends (e.g., WebKitGTK settings). Look at the tauri bundler code for AppImage to see if any environment variables or libraries are missing. Reproduce with a minimal Svelte app and compare scroll behavior.
