I'm not a Ubuntu user myself, but seeing the exact same issue on my Gentoo (unstable) system. I've seen it before the last couple of months, but only occasionally, typically after a long-running X session and it usually went away with an X server restart. For a bit over a week now the problem has been permanent however.
X.Org 1.15.0, xf86-video-intel 2.99.910, Mesa 10.1.0 (also seen with 9.2.5), Linux 3.13.3, Gnome 3 Shell OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile [ 27305.329] (--) intel(0): Integrated Graphics Chipset: Intel(R) HD Graphics 3000 Notice that there is a 256x256 area in the lower left corner of the window in which the window is not translucent. This corner always stays there independent of window resizes or going fullscreen. For the rest of the window it looks like its content are being "added" to the background. I've seen this bug posted in various places, like reported as a Minecraft bug or as LWJGL bug (the Java-GL glue library). It's certainly not a Minecraft bug, as it apparently appears with LWJGL demo applications as well. All the bug reports seem to have Intel onboard graphics in common. Note that there are also reports for a similar bug on Windows, but I doubt it's related. -- 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/1277905 Title: Game windows (minecraft, titan attacks, maybe others) on Intel are transparent and no longer playable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1277905/+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
