toads_tfi'm not well-versed in this kind of stuff but are you sure it's not a problem with your graphics card not being able to handle it? what card is it? have you updated your drivers(lol)?
i imagine it's something to do with your graphics card since you mention that multiple monitors were problematic
It's a 1070 so I expect it to be able to handle a stream and chrome at the same time. I will try rolling the drivers back later because they are currently up to date.
viperidk if this would help, but in your graphics driver settings, make sure your gpu is set to multi-display performance mode, or whatever it's similarly named as
It was already set for multiple displays, changing it to compatibility or single display didn't help.
