SUMMARY
If I have certain applications currently on focus such as VLC or chromium-based web-browsers, tooltips will have artifacts around the bottom borders, despite these bottom borders potentially not even touching the offending application's visible window. If I switch the active app to a different one such as konsole or evolution, these artifacts in the borders will disappear.

STEPS TO REPRODUCE
1. Disable blur or translucency or similar effects just in case.
2. Launch VLC or Vivaldi.
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.

I think this is a different issue, especially since they are only broken depending on what's the currently active window.

And by the way that bug is for wayland with scaling, this is in X11 without scaling.
