Steam streaming black screen?

Hi all,

Trying to use RPCS3 via steam streaming and from what I've researched, it should work but for some reason, I can't get it to work. The game plays on the host machine but it's a black screen on the client yet I can still hear the audio given the game is playing on the host machine still. If I take it out of full screen, it works perfectly or if I maximise the screen, it works perfectly but as soon as I full screen (alt + enter), the screen freezes on the client but continues to run on the host as normal.

Anyone know why this is occurring? Would love to get it up and running but I can't seem to figure out why it fails on full screen. I use Vulkan but have tried OpenGL and still the same issue, GPU drivers up to date also. Host system is below and have tested on three clients (Surface Pro, 2 x Windows 10 PCs with different setup) and the same issue on all. Other emulators work fine and this one but not when full screen.

Thanks
