Public bug reported: My PC is an Intel Core I3 and I use the built-in HD 4600 graphics. My display is 1680x1050, connected via DVI-D, Ubuntu version is 15.10 64-bit.
I do a fresh Ubuntu install and install and run glmark2. The horse spins smoothly. I set "System settings -> Displays -> Rotation" to "Counterclockwise", rotate my display and run glmark2 again. The horse totally stutters. When the rotation is "Counterclockwise" other OpenGL applications will even freeze. ** Affects: mesa (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1540194 Title: OpenGL stutter and freeze when rotation = Counterclockwise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1540194/+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
