Wine slow issue on m2 mac

[rgirard59]

Hello. I am looking into an issue where there is a small delay when I am transitioning between screens on a game in wine and looking at logging, it seems like maybe it's related to a ntdll.NtWaitForMultipleObjects call. This is on a Mac m2. I have tried pretty much all recent wine versions and well as crossover and they all do it. Interestingly though There is a scenario where it doesn't happen until I install directx9. Could also be around a ntdll.RtlAllocateHeap call. Does this sound like something that might be an issue that I could look into fixing in the source?

Seems to be something that happens between these two calls

1124735.427trace:d3d9:d3d9_texture_incref Exit d3d9_texture_incref.
1124735.655trace:d3d9:d3d9_surface_UnlockRect iface 011BD028.

1124735.663trace:d3d9:d3d9_texture_incref Exit d3d9_texture_incref.
1124736.023trace:d3d9:d3d9_surface_UnlockRect iface 011CD5F0.

1124736.028trace:d3d9:d3d9_texture_incref Exit d3d9_texture_incref.
1124736.370trace:d3d9:d3d9_surface_UnlockRect iface 0AC002B8.

Pretty consistent that the time spikes between those two but I don't see any code where this happens, so I am not sure where it would happen. In the game itself?

Looks like maybe something in here
