@we can live without the synchronization...
This was the suggestion to roll back the use of the sync extensions on mali. 
The current plan is to see how far we can get with hybris before OTA-11, and if 
we can't fix the performance in time, we'll roll back the sync extensions.

The synchronization should be lightweight, and it should be done even
with hardware clients. I think we're just fortunate that the commands
are getting serialized between the clients and the server in the GPU.

Bug description:
  Regression in OTA-10:
  tested on krillin and arale on rc-proposed.
  also I tried the fix for bug 1556763 but that's not related to this as well.

  The right edge switcher on both krillin and arale stutter when I drag
  it from the right edge and then swipe through the list of opened
  windows.

  This was not the case a few months ago, so we clearly regressed here.
