Magic Music Visuals

When using a spout input in MAGIC with an NVIDA external GPU on Windows 11 I lose signal randomly after clicking on other windows.
Stream comes back if I check/uncheck the direct X 11 box.
Problem lies somewhere within MAGIC because it's not dropping on other receivers.
I've tried reinstalling graphics drivers with no luck, any suggestions on how to fix?

Hmm I'm not sure but I'll look into it... we don't have any external GPUs around here though. Have you tried it on a normal GPU?

Appears to have been a driver issue, I went back to an old driver (391.35) and it's now working flawlessly.

Hmm ok. Nvidia seems to have a lot of problems with introducing new bugs in their drivers. I guess they don't test them very well.
