I watch the mesa-dev ML. What you want to do is to log and post from both
systems the following:
1. Xorg log (Typically called Xorg.0.log) from /var/log.
2. Run the program dmesg from the cmdline and log it to a file.
   HINT: Redirect to a file with > FILE. As in: PROG > FILE.txt
3. Install apitrace (cmdline command: apt install apitrace )
4. Run the program wile apitrace'ing it. (Normally you run the command in
   the terminal wine example.exe) COMPRESS the output it will be HUGE!!!
   HINT: apitrace wine example.exe | xz -9ecvCsha256 > FILE.txt.
5. Uname -a (This, in particular, will give you the kernel version.)
6. Programs and versions (wine, mesa, llvm, xorg, example.exe, libdrm).
   Typically you run from the cmdline: PROG --version; apt show PROG.
   The proprietary game will not accept this method of course.
7. Fill out a bug with this info at: https://bugs.freedesktop.org/. Use
   attachments liberally with the add attachment feature. You can comment
   and attach several times for 1 bug so not everything has to be in the
   first post.
   Describe your problem throughly.
   Don't post screen shots unless you have to.
   See these for examples:

https://bugs.freedesktop.org/show_bug.cgi?id=91251
https://bugs.freedesktop.org/show_bug.cgi?id=73739

Be aware that they might ask you to try a custom kernel/mesa/etc.. If you
cannot do this they might need a copy of the game in question. They are
friendly and will walk you through the above if you ask them to.

No, I have not run the above to check for errors but it looks correct and
I did check the man pages.

Thanks for your report,
David
