      Description

      We are seeing many refresh issues like JDK-8239900, JDK-8236592, JDK-8239901.

      While analyzing these issues i noticed that if we dont return based on nextDrawableCount(basically allowing multiple mtlDrawable presents to happen per frame), we see that we update the MTLLayer properly.

      But this is causing performance regression as we rapidly consume nextDrawables and lock our RenderQueue during blit.

      Find appropriate solution for refresh issue without causing performance regression.
