Visual glitches for fullscreen Konsole window
DESCRIPTION
Corrupt title bar covering window for some KDE Qt applications when fullscreen
(can replicate with Konsole, Dolphin specifically, but not many other
applications). Issue appeared with kwin version 6.7, downgrading only kwin to
kwin-6.6.5-4, the behavior no longer occurs.
STEPS TO REPRODUCE
1. Open Dolphin or Konsole
2. Snap window to fullscreen
OBSERVED RESULT
Visual glitch with repeating tiled graphics of the title bar over entire
window.
EXPECTED RESULT
Normal window, fit to fullscreen.
