Public bug reported:

The X Server consistently crashes when my Wacom Intuos Pro Medium tablet
is attached to my Dell XPS 13 laptop whilst I have a second screen
connected using the HDMI port on the Dell DA300 hub. The crash does not
immediately happens when the Wacom devices is attached, but during the
use of the tablet. It is easy to repeat this crash very fast by pushing
the tablet buttons and using the pen. In less than 15 seconds, the X
Server will crash. When the second screen is not attached to my laptop,
the X Server keeps running flawlessly.

My Dell XPS 13 laptop is running the preinstalled 18.04 LTS, Gnome
3.28.2 and it has Intel UHD Graphics 620 (WHL GT2).

I tried the tabled on a desktop with 2 screens attached running Ubuntu
20.04 LTS and Gnome 3.36.3. It has Intel HD Graphics 2500 (IUB GT1). It
works without issues. The bug does not arise on this device!

Please find attached gdb details (not sure if I did well; I have never
used this tool before).

Any idea how to fix this? Or maybe a workaround? My Wacom tablet is
almost useless on my laptop due to this bug. If I want to use it, I have
to detach my second screen and work on the small laptop screen.
