--- Comment #2 from [e-mail] ---
Version 10.8 is the last wine-staging that is working. From 10.9 onward the
following two errors appear and the ground textures are no longer rendering:

```
00fc:err:environ:init_peb starting
L"Z:\...\games\wow-1.12.1-nostalgeek-new\WoW_tweaked.exe" in experimental
wow64 mode

00fc:fixme:opengl:wow64_map_buffer Doing a copy of a mapped buffer (expect
performance issues)
```
