SUMMARY
I am seeing some artifacts in the bottom corners of some tooltips, like the
ones that appear when hovering the mouse over a systray icon. There is a
similar bug report (438644) about this happening in wayland with scaling, but
for me, this happens:
- In X11.
- Without scaling.
- Only when the active window has media-playing capabilities (e.g. in web
browsers or VLC, but not in konsole or kate), regardless of whether it
intersects with the tooltip or not.
STEPS TO REPRODUCE
1. Disable blur or translucency or similar effects just in case.
2. Launch VLC or a web browser.
3. Hover the mouse over some systray icon and watch the bugged bottom borders
(top ones render fine).
4. Optionally, launch konsole or some other app (don't even close nor minimize
the app from step 2) so that it becomes the active window, and then repeat
point 3 and observe that all the borders render correctly.
OBSERVED RESULT
Bottom borders of tooltips have artifacts.
EXPECTED RESULT
Tooltips should not have artifacts.
