Visual Panel Glitches

SUMMARY
The "resizing" animation shown when the panel switches from "floating" to "bar" experiences a number of visual/graphical issues and glitches.

STEPS TO REPRODUCE
1. Open an application in windowed mode on a blank desktop; note that the panel is "floating"
2. Resize the window to take up the entire screen (but not fullscreen so the panel is still visible)
3. Notice that the panel animation going from "floating" to "bar" displays some visual issues

OBSERVED RESULT
The "resizing" animation is not smooth and the panel either draws incorrectly or flashes during resize

EXPECTED RESULT
The "resizing" animation should be smooth with no visual glitches

Can not reproduce on Plasma 6.0, but there were some glitches that I noticed in the panel animation in previous versions- including 5.93.0.  But it's smooth as butter for me in 6.
