Description
This is hrev53713.
When moving window, backbuffer is flushed sometimes that cause flickering. Cause is probably in src/servers/app/drawing/DrawingEngine.cpp DrawingEngine::CopyRegion. It contains fGraphicsCard->Invalidate. Correct implementation would be shifting both back and front buffer.
Methods to reproduce:
- Resize window by left or top corner by using right mouse button.
- Move periodically updationg window on slow machine.

Note that https://review.haiku-os.org/c/haiku/+/2119 is related to this ticket (though there is disagreement about whether it is the right thing to do, or even a good solution.)
You might also try re-enabling (needs some work, though) the "async double buffered" mode already present in HWInterface. (see #if 0 blocks, and also the disabled SetAsyncDoubleBuffered call in AccelerantHWInterface.)
