Hello
I am using KDE Plasma 5.17.5 with Frameworks 5.62.0 and QT Version 5.12.5 (64 bit)

In "Systemsettings" I cannot open "Compositor". If I select "Compositor" systemsettings crashes.

Any idea what to do?


Regards

No idea what to do, but a short "me too" ;). Other settings than those under display work well, but on entering submenu 'compositor' or 'gamma', systemsettings immediately crash.

EDIT:  When I go to a terminal and enter
Code: [Select]
kcmshell5 kwincompositingthe compositor settings dialog opens, and changes can be made and applied. (kcmshell5 --list gives an overview of all systemsetting modules).

Update/Workarounds (kind of) to this:

I found this forum entry about a similar bug, https://www.linuxquestions.org/questions/slackware-14/%5Bktown%5D-selecting-regional-settings-crashes-system-settings-4175671456/ ,and when I do as mentioned there in a terminal
Code: [Select]
$ QT_QUICK_CONTROLS_STYLE=Base systemsettings5Systenmsettings work without error. So seems to be a bug that has to do with themes/styles.

Then there is KDE Bug #419625, https://bugs.kde.org/show_bug.cgi?id=419625#c2 , and there
Code: [Select]
...the problem appears when upgrading kscreen from 5.16.5 to 5.17.0

I've done further investigation and found the following:
in kcm/package/contents/ui/Output.qml:231, when I remove maskSource from OpacityMask item, the problem vanishes (tag v5.17.0)
Problem appears after commit 6309d33
and yes, I commented the said line in the file /usr/share/kpackage/kcms/kcm_kscreen/contents/ui/Output.qml and no more segfaults. At least more people noticed and working at it...
