FWIW this patch only fixes the issue related to the "failed to submit
rendering commands (Bad address)" message and nothing more.
If the issue starts to manifest without such message in the Xorg server
log, then it is highly likely to be platform-specific.

This is a news to me. Has this issue been submitted to the tracker?
If not, can you post it there?

You can collect panic and oops logs with a kernel that has
CONFIG_EFI_VARS_PSTORE enabled. If you don't already have one, you may
build qubes-linux-kernel via qubes-builder with the following line
added to `config-qubes`:
CONFIG_EFI_VARS_PSTORE=y
After booting the kernel, subsequent panic and oops will be recorded
in EFI variables, which will then appear as /sys/fs/pstore/dmesg-efi-*
at the next boot. Also note that the logs may be split into multiple
parts that are numbered in a reversed order. For more information, see
https://www.kernel.org/doc/html/latest/admin-guide/pstore-blk.html
