Wine has been crashing with 10.16 in wayland when staring WoW.exe

The only line in logs is:

Warcraft_retail_\WoW.exe: ../wine/dlls/ntdll/unix/sync.c:606:

wine --version
wine-10.16 (Staging)

Same issue here, but different application, running CoinPoker. I don't get an
immediate crash, but the application will crash after some short amount of time
(5-15 minutes, didn't time it). Downgrading to 10.15 avoids the issue.
Application crashed on 4 consecutive occasions before I downgraded. Also, not
currently using wayland, but still on xorg or whatever came before that...

Running from the console shows a similar line:

-4d0e-a443-e7e1e8389108: ../wine/dlls/ntdll/unix/sync.c:606: cache_inproc_sync:
Assertion `!refcount' failed.

I've downgraded from arch 10.16 (wine-10.16-1-x86_64.pkg.tar.zst) to 10.15
(wine-10.15-1-x86_64.pkg.tar.zst)to avoid the issue.

Same issue here, noticed with WoW.

Freeze/crash happens randomly, it seems.

Goes away when downgrading to wine-staging 10.15.
