[Bug 1295851] Re: Input lag after last update

 

Actually I would not be surprised if we did still have a bug like this. The team would not have noticed it for several reasons:
  * We don't have any keyboard/typing-related demo clients.
  * We don't use XMir regularly
  * Touch input could be suffering similar lag and we would not notice because touch events are much more numerous and more likely to be flushed adequately to keep Ubuntu-touch moving.

Our MultithreadedCompositor's frame scheduling logic is still somewhat
suspicious. It gets the number of frames to schedule from the
BufferQueue, but that function of the buffer queue is apparently racy by
design, and may not return a realistically high enough value adequate to
schedule enough frames.
