    Description

      Animations too fast, and timers also too fast while animation running.

      You need to have Nvidia card, and display connected into motherboard video output (not direct to video card) to reproduce this bug.

      First attached example to demonstrate too fast animations.
      Second example to demonstrate difference from QTBUG-42699, Window and rotation added for start render, because I can't reproduce with the original code.

      With "simple" render loop app works fine.
