Dear Maintainer,

After updating to mesa 22.2.0~rc1-1 on my UTM virtual machine on macOS
(which uses VirtIO graphics), LightDM and anything else using Mesa is
just completely black except for a cursor. This is still present in the
latest version. The default graphics option of UTM is virtio-ramfb-gl,
which is GPU accelerated; I tested virtio-ramfb, and it doesn't have
this issue, though it's not ideal as I can't resize the window and it's
not GPU accelerated. I tested all of the *-gl accelerated graphics
options, and they all have this issue. I also tested a normal
virt-manager VM on Linux, and it doesn't have this issue.

You don't provide many details, but at a quick search your issue may
be this one:
https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/291
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19655

Which is fixed in the version 22.3.1-1 currently in Debian testing / unstable.

Ben, can you check and report back?

Hello Fabio,
I don't see how that issue is related to mine. It supposedly only occurs
when XWayland is being used, while mine is happening on pure X11.

Thanks,

So, is your issue still reproducible with 22.3.1-1?
If yes, is there a similar issue already reported at
https://gitlab.freedesktop.org/mesa/mesa/-/issues ?
If not, can you open a new report there?
