This bug is already present in 14.10. My system is a HP Pavilion laptop with a muxless Intel/AMD combination (Intel Sandybridge HD graphics and AMD Radeon HD6770).
A Workaround that works most of the time is to press Win+D again and again to switch between desktop and game application. After a few iterations the problem is usually gone: once a game (or steam) starts drawing, everything works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1430888 Title: DRI_PRIME with radeon/intel windows do not draw To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1430888/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
