Bug Description
I have crashes of kmail when displaying mails (e.g. GMX info mail). After some research I found that it is related to the qtwebengine when using nouveau driver.

It also crashes when running on wayland, the cause is not yet known.
Work around these issues by not doing GPU-accelerated rendering in such cases.
This happens on 18.04.3 (bionic), 19.10 (eoan) and 20.04 (focal).
