I really don't know why this occurs.
Konsole (weird white ugly lines)
Sometimes i get that anakondi or krunner crashed.
Is there something i can do to fix this? Please help.
Update: Same issue on Ubuntu 20.04 after I did the update.
PS: I previously had XFCE installed on the same ubuntu.

and not supported anymore. You should upgrade to a supported version ( 20.04 or 20.10) or reinstall older but still supported version of Ubuntu (16.04 or 18.04). – mook765 Dec 03 '20 at 19:35
