I made my own display and it worked great the first time, but then the second time I opened it it not only didn't work, but the preview of what I am recording was white, along with the space surrounding it, closing obs made it stop responding, and was also making obs very slow, although that seems to have stopped now.
I have tried reinstalling, turning it off then reactivating it and deleting the source and reinputing the files but nothing worked. seems like something to do with optimization. can't say I can recomend until I have this issue fixed
(it worked great the first time though)
