Web contents rendered with QtWebEngine and the amdgpu driver have heavy
glitches since a recent update. Some examples:

- Scrollbars have glitches until a mouse over happens
- embedded videos have glitches until mouseover
- YouTube videos will lag heavily when the playback controls are displayed

The problem appears in programs that use QtWebEngine (libqt5-qtwebengine) l=
ike
KMail and Falkon.
It does not appear in Firefox which uses its own rendering engine.
It does also not appear on another machine that has an Intel iGPU when using
programs that use QtWebEngine.

Therefore I believe the problem is related to the amdgpu kernel driver and =
it
manifests only when using QtWebEngine, so I filed it as a kernel bug.

I'll attach some example screenshots to illustrate the issue.
