Created attachment 143203 [details] Screenshot of the panel with the extra horizontal artifact SUMMARY When kwin is restarted while Plasma already runs, the panel starts showing a strange horizontal line near the top. It disappears when restarting Plasma. STEPS TO REPRODUCE 1. In a running X11 session, restart kwin. OBSERVED RESULT A new horizontal artifact appears spanning the entire panel. See attached screenshot. EXPECTED RESULT The panel should look as before.

Actually the problem looks slightly different: The Panel SVG isn't tall enough anymore. You said you can reproduce this just by restarting KWin? does it get fixed by restarting plasmashell (`plasmashell --replace`)?
> You said you can reproduce this just by restarting KWin? Yes. KWin is sadly crashing fairly regularly since the update (fix is supposed to be in 5.23.1) and the glitches do appear each time that happens. > does it get fixed by restarting plasmashell (`plasmashell --replace`)? Yes, though my restart script looks slightly different: killall plasmashell sleep 0.2 plasmashell &
Sounds like sn SVG cache bug, then. Moving to Plasma Framework, where the logic lives.
fixed in plasma6
