I'd just like to state that an update from the stable Trusty kernel (3.13.0) to a mainline kernel (Trusty .deb) (3.13.8) seems to have reduced much of the tearing, making games and applications much more usable, at least on my machine. I'm not sure if this has anything to do with the recently proposed dma-buf hardware synchronization patches.

My issue is that whilst the new switching feature works very well, it still produces an extremely noticable amount of visual stuttering. In graphical and applications and games I can produce very large frames- per-second numbers yet the amount of visual tear makes the program unusable. Vsync/Sync to Vblank/vblank_mode=1 also does not work as intended, with tearing still present. Has anyone else had this issue or found a fix?
