SUMMARY

Display corruption of Icon-Only Task Manager on mouse hover

The 2024-10-31 update of neon-desktop along with other packages brought about this new behaviour: when hovering mouse over the panel corrupts its visual representation completely. 

Switching to another virtual desktop and back re-displays the panel correctly, only until the next mouse hover.

STEPS TO REPRODUCE
Hover the mouse pointer over the panel in any horizontal direction.

OBSERVED RESULT
Visual corruption of the panel. All panel icons seem to be drawn at panel origin after mouse hover, rather than in their original locations.

EXPECTED RESULT
No visual corruption on mouse hover.
