            Bug ID: 110459
           Summary: Escape from Tarkov on DXVK renders wrong windows
                    reflection unless RADV_DEBUG=nohiz is passed
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

With RADV_DEBUG=nohiz

Since I didn't had that problem before, I originally hoped it was the same
regression as the one affecting Lords of the Fallen, Bug 110259: originally
found about it in DXVK issue here: https://github.com/doitsujin/dxvk/issues/985
but unfortunately commit 62a9d757e6074215c145c9637014d9acb16d865d did not fix
it, but running with RADV_DEBUG=nohiz fixes it.

I tested it on several latest mesa and DXVK git versions now, last one was
4c3c417b00fd2594d8fa5ab86479fb7c448d1f09 for mesa, hard to tell when exactly
the bug started appearing, but I may do some testing, especially if it happens
with the stable one too. Fresh reinstall of the game, DXVK and even using a
different Linux install did not help. My card is AMD Radeon RX 580.

Basically, it's the squares that appears on the place where windows are that
are moving with my character view, in at least one map (Factory). I didn't test
the game extensively without RADV_DEBUG=nohiz whether the bug happens
elsewhere, but I may now for debugging, but the game runs fine otherwise on
RADV with RADV_DEBUG=nohiz. I didn't test how it runs with AMDVLK either.

I'm attaching the screen how it looks like with RADV_DEBUG=nohiz and how it
looks like without it.

The game is basically a Unity 5.6.6f2 online game with custom anticheat, so I
normally don't want to mess too much with it, but it does have an offline mode
(sadly you need to have an account to play though). If there's anything I can
help with it further, let me know!
