D3Dmetal "Display not active" with UTM 5.06

[Stefidar]

D3DMetal is not working any more in Windows 11, Windows load but there is a "Display not active" forever. Switching to DXMT works. (macOS 27.2 beta 2). (I did uninstall and reinstall the driver).

I confirm switching to DXMT from settings DirectX driver option works.

Sorry I meant to push a corresponding windows driver update but I am traveling and do not have access to my signing key right now. If people want to build it themselves (instructions are in the repo: https://github.com/osy/kvm-guest-drivers-windows/blob/neptune/viogpu/viogpu3d/BUILDING.md) and test sign it, please let me know if it works.

That's OK, I will wait till you get back, hahaha.

Found the cause: since macOS 26.4, shm_open() rejects O_CLOEXEC in apps built with the 26.4 SDK or later. UTM 5.0.6's renderer is built with the 27.0 SDK, so D3DMetal can't allocate shared memory. It's a host-side bug, separate from the guest driver update. Fix: utmapp/d3dmetal-native#2

@lovon-spec thanks for finding that

Any ETA for this? I know we can build it ourselves, but still.
