Thank you for this work! I notice this since a month ago and haven't had time to delve into it. Horrible stuff. I wonder if it makes sense to update the intel driver to see if it fixed it? Then perhaps we could avoid the hack. There are commits here that touch SNA and things that look like they could be relevant: https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/log/ As you probably know, the intel driver doesn't get proper releases :( You just have to take a tag from git. That's what we do now and perhaps updating the driver could fix this bug. Andy
