I'm using Ubuntu 12.10 with an AMD A8. When I use either an nVidia 460 or AMD 7870 I experience this issue (have tried many drivers with both of these cards, including the latest beta drivers). I have tried to make a video of the issue, unfortunately my phone's camera doesn't capture video at a high number of frames per second, so the issue doesn't look that noticeable in the video:
http://www.youtube.com/watch?v=T9Q879m9J2k SuperKey + S and SuperKey + W are really stuttery in 2560 x 1440 mode. I've also noticed that is doesn't occur on my laptop (Intel HD 4000 integrated graphics) when it's only driving a single monitor (even at 2560 x 1440), but does occur when I connect a secondary monitor (the laptop screen is 1920 x 1080, the secondary monitor is 2560 x 1440). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1039942 Title: [regression][GLES] scale mode is slow and stutters when unityshell is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1039942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
