- the nvidia driver is outdated, so first of all you should update it - this "A log out doesn't fix it, after a reboot it is ok" is a good hint for a driver bug** - you're probably not using them anyway but avoid the blur/sharpen plugins - as a workaround, suspend/resume compositing around changing UI settings (shift+alt+f12) **actually this looks like overheated hardware but that doesn't match "whenever i change some UI settings" condition you maybe don't have to do a full reboot. "telinit 3; modprobe -r nvidia; modprobe nvidia; telinit 5" might do either (ie. change to GUIless runlevel, unload the nvidia driver, reload it and change back to GUI powered runlevel) -- dev note: This is likely an upstream bug, but rather related to compositing than plasma(-desktop), or iff, than because of ARGB drawables -> reassigning
I updated to the 260.19.21 driver. After reboot, i opened two windows in KDE and when i want to switched (in the teskbar) plasma freezed and nothing worked (even alt+sys+REUISB) i rebboted from the button of the central unit. I rebooted again, i tried to change some settings in effects or styles and i get a freeze again (looks more like the bug https://bugs.kde.org/show_bug.cgi?id=246498) I tried from another user (xguest) and everything worked fine. I logged in again with my normal account, i opened systemsettings → effects, and i clicked on the button default in the bottom. Since this, i cannot reproduce any of the above behavior. Everything looks ok , plasma is very fluid, no problem at all. I think the problem is gone, if you prefere to wait more time to confirme but i dont think that is needed. Thanks for the support.
it's been caused by some setting (in the advanced tab) or an non-default active (3rd party?) effect then, so you might face the issue again when playin around on settings or (re-)enabling the offensive effect. if you can bisect the xause this way, feel free to report ;-)
