Does anybody know what the bug on the attached picture is and how it could be fixed?

This is a common graphics corruption issue that happens with some graphics card. I can reproduce such an issue reliably on a laptop with a broken Intel graphics adapter, so IMO this usually means that the graphics card need replacing.
See if you can clear the problem by restarting the Plasma desktop using the terminal command killall plasmashell; kstart5 plasmashell
. If it recovers, it could be a bug in Plasma but if it doesn't - it is definitely a hardware issue.

Then its likely a bug related to suspend/resume on Nvidia - one of the following bug reports could be relevant (or all of them): bugs.kde.org/show_bug.cgi?id=364766 bugs.kde.org/show_bug.cgi?id=344326 bugs.kde.org/show_bug.cgi?id=382115 bugreports.qt.io/browse/QTBUG-56610 , and they suggest that the problem was already fixed and you should update your OS.– GussJan 18, 2019 at 9:52
