Can you try the latest master? There was a bugfix for VR use cases very recently.
This build runs fine: https://github.com/doitsujin/dxvk/actions/runs/14813428227
I'll close the issue, then. Just keep in mind that error is there for v2.6.1 release version.
I get the following error when trying to launch VRChat in VR mode with DXVK v2.6.1:
The status returned from this call seems to be
0xc0000005right after the first attempt to submit the texture:https://github.com/ValveSoftware/Proton/blob/proton_10.0/vrclient_x64/vrcompositor_manual.c#L1680
The error can be reproduced with this build: https://github.com/doitsujin/dxvk/actions/runs/13967826524 (commit https://github.com/doitsujin/dxvk/commit/90ee5fe18021486fc4e61bc168f63bb21642a882)
But not with this one: https://github.com/doitsujin/dxvk/actions/runs/13911326406 (commit https://github.com/doitsujin/dxvk/commit/64c9dc91cfa595d2a9f2e62779e54681e519c609)
