Can comfirm this issue and that the image from post #12 is identical to the issue I see in minecraft as well.
Intel® Core™ i5-2430M CPU Ubuntu 14.04 fully updated as of this morning I have seen this issue for ~1 week. Unity7 DE No ppa's that affect video card drivers, or kernels. A pretty stock installation. -- You received this bug notification because you are a member of Desktop Packages, 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 Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: Fully up to date Trusty. Open Minecraft, notice that the window is transparent - you can see through to the desktop wallpaper, making the game unplayable. Also tested with Titan Attacks which is also a lwjgl based game - dunno if that's coincidence This worked a few days ago. Probably before the most recent xorg update. See screenshots.
