I'm getting this on my intel based X220 when running this game demo:- http://www.imake-games.com/nubs-adventure/
To reproduce download http://www.imake-games.com/nubs/earlyBuilds/NubsAdventureEarlyAccess.jar.zip Unzip it then run it with java -jar NubsAdventureEarlyAccess.jar The game graphics are corrupted (as seen in the attached screenshot) and I get the same "_xgeWireToEvent: Unknown extension 148, this should never happen." error in the terminal. Easily reproduced, doesn't happen on nVidia based desktop ** Attachment added: "Screenshot from 2014-09-17 23:52:58.png" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1369113/+attachment/4206854/+files/Screenshot%20from%202014-09-17%2023%3A52%3A58.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1369113 Title: Steam game began crashing 2014-09-12 (cross-post Source bugtracker) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/steam/+bug/1369113/+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
