--- Comment #3 from magib...@hotmail.com --- I have to add that Right Click on Desktop > 'Configure Desktop' has this issue as well, with the difference that it's the plasmashell process that takes 100% of CPU and freezes. I made a backtrace of /usr/bin/systemsettings5 while it's frozen. It looks like a graphics-related issue. I tried to reproduce the issue in another computer with integrated graphics Intel HD Graphics 4000 (i965 driver), but I couldn't. It works well there. > #0 0x00007fffd8a97677 in ??
