           Summary: DRI_PRIME=1 and fullscreen issues
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi

I have multiple issues while using DRI_PRIME=1 (radeon):
1. Few windowed mode applications don't draw content until window is resized.
Also right-click context menu doesn't always appear
2. I have screen tearing for fullscreen apps running in , screen is cutted from
screen corner to corner, crossing at the centre of the screen.
3. tearing and flickering when running programs.
4. fullscreen games often freeze screen when minimized or closed (tested on
multiple games like Talos Principle, Dota, Tomb Raider, 0.ad, etc). After
freeze i usualy go to tty and restart lightdm. Maybe it is also intel gpu
related?
