Update: recently one of programs I use started to complain that screen was not DRI3 capable. I am using Intel driver which apparently defaults to DRI2. I forced it to DRI3 using
Option "DRI" "3" After that I immediately got tearing during video and the same strange corruption of screen (fast blinking). As modesetting driver defaults to DRI3 it appears the issue is not Intel vs. modeseting but rather DRI2 vs. DRI3. Googling around suggests that this may be this upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=97957 If there is Ubuntu package for 16.04 that includes above commit I would be more than happy to test it. ** Bug watch added: freedesktop.org Bugzilla #97957 https://bugs.freedesktop.org/show_bug.cgi?id=97957 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1665850 Title: Screen corruption after unblank with HWE stack To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server-hwe-16.04/+bug/1665850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
