The backtrace ending in OsLookupColor() is a red herring, this is just how
the backtrace code works, the problem is rather in the modesetting driver
I'd say.

You'd need a backtrace with symbols, preferably from gdb. You might want to
check in coredumctl.

Also, having this part of a discussion in xorg-devel is not ideal, there's
an issue created for that in gitlab, that would be more appropriate to keep
track of the technical discussions I think:
