Description nyanpasu64 2023-05-27 21:47:38 UTC

SUMMARY
With a 44-pixel-tall panel and Icons-Only Task Manager, clicking the leftmost pixel of an app icon triggers (eg. opens) the app and the app to its left at the same time.

STEPS TO REPRODUCE
1. Move the mouse cursor to the bottom of the screen.
2. Move it right until the first pixel the app to the right is highlighted.
3. Click to open/focus, or middle-click to close (reconfigurable).

OBSERVED RESULT
Both apps are opened, focused, or closed.

EXPECTED RESULT
Exactly one app is.
