--- Comment #31 from JKAbrams <j@jkabrams.se> ---
I've had this issue a few years and it is still there. This is the only major
annoyance I run into repeatedly with KDE, it happens on average ~2-3 times a
week (while working full time).

Mostly it happens to Firefox and VirtualBox. I've also seen it happen on
Libreoffice, Audacious and Eclipse, but it can seemingly happen on any
application in heavy use. It also happens to Plasma itself where the taskbar
stops updating (opening/switching windows lags one window behind), hover will
not redraw it but clicking on the taskbar will.

I've had the problem happen on two different machines (both with nVidia
graphics but it happens with both the proprietary driver and nouveau) from
early versions of KF5 up until present Plasma 5.8.7, Frameworks 5.36.0, QT
5.6.1, Kernel 4.11.0-14. Arch Linux and Linux Mint 18.2.

I currently runt compositing on OpenGL 3.1, but OpenGL 2.0 also had the
problem. Others (#330424) report that Xrender is also affected.

From my user perspective these are possible duplicates as they describe the
same symptoms:
