D23881: Possible solution for scheduling repaints on NVIDIA

davidedmundson added a comment.


  Do you know if this will work well on PRIME systems?
  
  Without wanting to derail this thread too much I've spent some time debugging a separate bug in QtQuick qsgthreadedrenderloop  - we swap the buffers, then render immediately expecting the next call (glClear) to block. And on prime laptops it simply doesn't.
   __GL_MaxFramesAllowed=1 didn't seem to make an impact there. That doesn't have this fence sync stuff, but I doubt that would make a difference?
