[Bug 107844] assertion failure when running piglit over virgl

--- Comment #10 from Marc-Andre Lureau <marcandre.lureau at gmail.com> ---
I compiled mesa git on the host, reproduced the crash

Host virgl, qemu, mesa, are git master version.
Guest mesa is git master version.

I run in f29 VM started as multi-user target, and run Xorg and mutter manually
(Xorg -nolisten tcp -noreset :42 vt5 -auth /tmp/xauth). xorg 1.20.3-3.fc29
mutter-3.30.2-2.fc29
