I'm seeing this on Trusty, on an HP Z420 and an HP Z620, both with nVidia cards.
It occurs primarily when transitioning between workspaces. I've found that I can (mostly) work around it by always transitioning first to a blank workspace (one with no windows, just the background image), and then to the workspace I wanted. Moving directly from one workspace with windows to another with windows triggers corruption most of the time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871972 Title: 8086:0116 [i915] Screen display corruption resizing LibreOffice Calc window Acer Aspire 5750-9668 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/871972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
