This bug is affecting me too. I can confirm that the SNA approach is working as a workaround, but as said before, performance is heavily impacted.
My system has a Intel Broadwell processor with integrated Intel Graphics (5xxx-series). I did not have the problems on my Haswell system with Intel Graphics 4xxx-series. Also an interesting thing: The bug only occurs when using XFCE. I could not reproduce it using gnome-shell! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1452318 Title: Faulty behavior when resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1452318/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
