In addition to MediaPlayer, any window that repeatedly call BView::DrawBitmap like Haiku3d or Qt windows also cause flickering.

BView::DrawBitmap cause flushing of screen backbuffer outside of drawing area in app_server while it shouldn't.

I identified problem. DrawBitmap and other drawing operations flush back buffer bounding rectangle instead of region that flush area that not belongs to window: ​https://git.haiku-os.org/haiku/tree/src/servers/app/drawing/DrawingEngine.cpp#n638.
