When something like that happens to me it's usually because compositing has been disabled due to some past glitch. If I re-enable it via Settings -> Display and Monitor -> Compositor, then all is well. This happens infrequently but I often fail to notice immediately, I've setup a login job that checks it: ---- snip --- #!/bin/bash #set -x compositor_enabled=$(qdbus-qt5 org.kde.KWin /Compositor org.kde.kwin.Compositing.active) if [ "$compositor_enabled" != "true" ] then notify-send -a "Check Compositor" -t 0 -i dialog-error.png 'Hardware -> Display and Monitor -> Compositor is disabled!' fi ---- snip --- On Friday 03 September 2021, Philippe Andersson wrote:
Hello List,
Since the latest nVidia driver update (2 days ago), the desktop seems to have lost transparency support (Leap 15.2 / KDE 5 / Plasma).
Kernel: 5.3.18-lp152.87-default nVidia driver: G05-470.63.01 (from nVidia repo) HW: Lenovo P53 with Optimus graphics + suse-prime-0.7.14
Anyone else noticed that?
TIA
Ph. A.
