Re: OpenGL performance with Gala


Great! I hope https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1034099
gets fixed till Luna beta2 so we'll be able to integrate ulatencyd by
default that will assign these priorities automatically. Ubuntu
doesn't seem to be interested in fixing that; perhaps we should
catalyze the activity by bisecting the change that caused this bug.
