[d3d9] SkyDrift: crashes on alt+tab

[ranplayer]

Game crashes if you alt-tab (works fine with WineD3D). I've uploaded an API Trace, but it doesn't crash with it. From the Proton logs, the highlighted errors would be:

err:   DxvkMemoryAllocator: Memory allocation failed
err:     Size:      3145728
err:     Alignment: 16
err:     Mem types: 0,2,3,5,7,8,9,10

Thank you for the issue.
d3d9.allowDirectBufferMapping = False works around this. Just waiting for a dev to evaluate whether that would be the correct way or not.

[ranplayer]

@Blisto91 I've just confirmed this workaround works on my end. Thank you for the quick feedback.

[K0bin]

It didn't crash when you made that apitrace, did it?

[ranplayer]

Yes... it didn't

[K0bin]

Can you make one with DXVK where it does crash?

[ranplayer]

Sure... how could I do it with DXVK ? The previously generated one I followed the wiki tutorial.

Just set the dll overrides to native instead of native,buildin.

[Blisto91]

When using Proton just dropping the dll's next to the exe should be enough as when dxvk is used as the direct3d library (default) the overrides are already set.

[ranplayer]

@Blisto91 I did exactly what you said to generate the already attached trace (but the crash doesn't happen)

[Blisto91]

Managed to get one where it crashes with dxvk on Windows https://drive.proton.me/urls/NPBQT1CCNC#ysWLsQjt30Ks
