.4% of compositor thread time is spent running "antifilldot8" algorithm
The first issue is that we do not do any GL compositing on Linux because at current it is too buggy to enable by default. So for that reason alone everything is composited in software. For WebGL, We do a readback to a shmem to send WebGL stuff to the compositor because currently we have no reliable way to do otherwise, even with xrender, since GLXPixmaps turned out to be too unreliable to enable by default as well. So that the other reason this is just being composited in software.
Depends on: 1323284
Priority: -- → P5
I wonder what is worse: Exposing broken drivers on a few systems, therefore creating preasure to fix those issue which would benefit the whole linux graphics stack, or doing a readback of a GL surface in order to be able to perform composition in software?
