There are many apps I can use to trigger this drm error. It occurs more
often on a Wayland-based desktop than on X11. While looking into this,
the most reliable way to trigger it was to open the "About" dialog
window in KeePassXC, then to select the contributors tab, and then to
scroll a bit. The content of the scrolling area is often only partially
updated, which makes the text unreadable.

I tested this on a Windows 10 host with an Intel Iris GPU running the
latest VMware Workstation 16.2. The virtual machine contains a current
Manjaro Linux GNOME desktop with Wayland enabled. 3d acceleration is
active. However, this behavior has been there for quite some time, but
for some reason it is more disruptive today.
