hi guys

Looking glass host B7-rc1 fails to initialize the d12 copy backend with the following information:

does the d12 copy backend require a more modern build of windows 10?

i’m very happy to help debug

More details TBD as copy paste doesn’t work in wayland

Resizing bar0 to 16GB does indeed attempt to initialize d12 however looking-glass-client now shows screen corruption until the client crashes:

tried 8GB and 16GB to the same end.

I can confirm SAM is active in Adrenalin
