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

damnit i looked (almost) everywhere

i’ll see how this goes, many thanks

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
