final blocker 1491320 - either mutter or gnome-boxes need to be adjusted

[Kamil Paral <kparal@xxxxxxxxxx>]

I've already tried to contact people on IRC, but I was getting "we don't care, go away" feeling. So, once again, just to make sure Workstation SIG is aware. There's this blocker:

heavy screen flicker with latest kernels in qxl+spice VM
https://bugzilla.redhat.com/show_bug.cgi?id=1491320

We don't have much time until F27 Final release [1]. The kernel folks are not sure if this can be fixed easily or quickly. It would help if software stack could be adjusted to avoid this issue:

a) gnome-boxes and virt-manager defaulting to virtio-vga instead of qxl

b) mutter falling back to xorg when qxl driver is detected

It would be great if we didn't have to deal with this at the very last day, so please, look into this. I expect a) to be quite easy, but please note this will not fix the problem for anyone using an already created VM, or using a different distribution. Those will still see F27 Workstation with horrible flickering display. b) would help with that, but I assume that's a bit more work.

Thanks,

Kamil
