Dear Maintainer: I need to advise you that the current package in Stretch xserver-xorg-video-qxl 0.1.4-3+b1 is ***NOT*** fixed
on my Stretch I manually recompile xserver-xorg-video-qxl and applied the following patch: http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/plain/no-surfaces-kms.patch using this patch on the recompile package, the issue no longer happens (when kms enabled). To be specific, with this patch enabled, even though Xorg.0.log report that surfaces enabled, they behave as if disable and all works. This is the same behavior I can see when I ran a Fedora; log say enabled but no issue, because in fact disable internally. I advise please apply the patch above to package (if there is no other patch in works). This can't be in the next Debian. In addition I advise to check other patches listed: http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-qxl.git/tree/ to see if they fix anything else, such as qxl-kms-disable-composite.patch I can confirm there is other issues with QXL driver (other than this bug) with 4.x+ kernel such as broken auto-resizing ("Auto Resize VM with Window" broken). Thank you
