SIG is aware. There's this blocker:
heavy screen flicker with latest kernels in qxl+spice VM
We don't have much time until F27 Final release . 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.
As has been discussed in the bug I don't think we are going to be able
to sufficiently solve this issue with workarounds in the virt tools like
virt-manager and gnome-boxes.
At this point it seems we either need a kernel fix/workaround to
materialize, or some change on the gnome side to not default to wayland
session if we are running with qxl video.
Can someone from the desktop side comment on that idea? (in the bug
