I have exactly the same issue on my core i5-2520M with hd 3000 sandy bridge graphics.
These artifacts are very annoying and only occur at the edges of transparent textures, like you will see on the screenchot. Same thing occurs in Osmos, but only edges of all textures are visible. Next thing: when i use the minecraft internal screenshot feature, the screenshot captures the texture error, but for the next ~10 seconds the graphics are COMPLETELY normal as they should be, but after short time the sky-colored artifacts shine through again. ** Attachment added: "Minecraft texture errors on hd 3000" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/829086/+attachment/2544122/+files/2011-10-14_17.20.30.png -- 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/829086 Title: Artifacts in 3D with Sandy Bridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/829086/+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
