Thank you! 

I had same issue on other distro I do not use anymore (mageia) so upstream is 
better, but it looked like it was never going to happen (they do not appear in 
his git yet or I miss it).

The patches need to make it into an upstream release first.


I would also prefer that.

I already contacted upstream about it, he's aware of the patches and 
merging them somewhere on his list.

The patches need to make it into an upstream release first.

Please include this patch as well:

http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/plain/qxl-kms-disable-composite.patch

it appear to help with glitches.

Is there any chance these two patch can make it into Jessie? The reason is 
because it affects all jessie live CD and live CD can't be used properly at all 
with KVM/spice, it really break functionality and there is no workaround there 
unless you rebuild the CD. There is still 2 years of life to jessie and all 
downstream suffer.

Bug#801081: Re: xserver-xorg-video-qxl: QXL video unusable due to performance

Hello,

I tried some time ago to install the qxl driver from testing into Jessie but it 
hang with green screen on boot.

I tried a few days ago to make a new vm of Stretch and it still has the problem.
To make qxl usable I have to disable the offscreen surfaces as in the conf.
It speeds up everything to near perfect. For example the main page of wikipedia
can't be browsed in iceweasel, it's too slow.

There was also more artifacts in the Stretch vm. Seem fixed by disabling 
offscreen surfaces.
I add that .conf to all my VMs manually now.
