So use of QtQuick is slow, especially when using the desktop theme where we have large texture uploads. Probably means we have a software GL driver. They do suck. You can try kcmshell5 qtquicksettings and selecting the software backend. This means we avoid GL and use a slower software fallback, but that's often quicker than using GL that in turn is software emulated. Let me know if it helps.

That actually solved the problem immediatly. Thanks! I think this should be reported to QT to see if they can fix it.

I'll check discover loads the KDE quick settings overrides. Git commit d783ebd003c9ffc66a0fdd5aca28045f10bf9937 by David Edmundson. Committed on 12/11/2018 at 11:21.
