Hi, I tried to change some UI colors, themes and other settings but it didn’t work. I remember this problem occured after I have installed Clementine music player and it needed to install another package dependency, but don’t remember which one exactly. How can I fix that?
Are you using a Nvidia GPU by any chance ?
Can you share your system info ?
Try running kcmshell5 qtquicksettings. See if rendering is set to software and if so change it to Automatic.
This looks similar to a problem I encountered and it took me nearly a year to solve. [SOLVED] Visual bug in QML based GUIs (bug reported, workaround found) (Page 2) / Applications & Desktop Environments / Arch Linux Forums
GPU: Intel 3rd Gen Core processor Graphics Controller
it’s already set on automatic
