Setting max_flush_vertices to 1 fixes the problem here, with the mentioned noticeable performance loss. IIRC, hibernating/resuming can accelerate the appearance of the bug, but I'm not quite sure about this, it might also be coincidence. I will now try to decrease the value from the default one to find the sweet spot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1098334/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
