Description Kryštof Jelínek 2024-10-01 07:03:43 UTC

SUMMARY
The task manager panel does not hide when the setting to keep thumbnails for all windows (even minimized) is set. It is then in a buggy state where it considers itself hidden, but is still being rendered. Moving the mouse to the bottom of the screen then "reveals" it in the sense that the "reveal" animation plays. The taskbar stays shown forever.

STEPS TO REPRODUCE
1. Set the value of Screen & Monitor > Compozitor > Keep window previews to "all windows"
2. Observe the broken taskbar

OBSERVED RESULT
Non-hidden, continuously rendered taskbar.

EXPECTED RESULT
Hidden, not rendered taskbar.
