            Bug ID: 43519
           Summary: Path of Exile: Corrupt/flickering UI textures after ~1
                    minute of gameplay
           Product: Wine
           Version: 2.14
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3dx9
          Assignee: wine-bugs at winehq.org

console log for Wine, manual annotations added (in the form of <<<NOTE>>>
lines)

Path of Exile 3.0.0c launches and enters a game successfully on 32-bit mode
with Wine 2.14-devel on macOS.

However, about a minute or so into gameplay, the UI textures start to flicker
uncontrollably, and are replaced with corrupt nonsense (see attached video "PoE
Corrupt Textures.mov"). At the point where this starts happening, the console
shows the following:

err:d3d:wined3d_fence_wait glClientWaitSync returned 0x911b.
err:d3d:buffer_sync_apple wined3d_fence_wait() returned 4, dropping async
buffer locks.

Before this message appears, everything is 100% OK.

Environment:
- macOS 10.12.5 (Sierra)
- MacBook Pro Retina, screen resolution 1920x1080 (external monitor only)
- NVIDIA GeForce GT 750M graphics card with 2048MB VRAM (discrete graphics in
use)
- Wine 2.14 development version, WINEARCH=win32, 32-bit .wine directory (bug
still occurs with today's Wine 2.14 staging; 64-bit Wine fails to launch the
game at all)
- Vanilla .wine directory (winecfg not run, winetricks not run, no DLL
overrides)
