--- Comment #9 from Sveinar Søpler cybermax@dexter.no --- (In reply to Kron4ek from comment #8)
I figure out that the first bad commit is a27d5bae114eef5352b699ee38975bc8793b4dcb (winevulkan: Use standard CRT memory allocators.). And i see "free(): invalid size" in the Wine output when i run the launcher.
Can't be that one, cos i tried with my custom proton'ish hack wine-6.5, and i do not have that commit at all.
I do however have the same problem with only being able to choose DirectX11.
Booting my older staging-6.4 wine, i could choose d3d12 tho.
