Bug Report XSHM capturing "background" only

[Limeth]

When I add an XSHM source, it either captures the workspace background only, or some sort of cached view of a previously opened window, as if it was being saved in RAM and read by XSHM. Window capturing using Xcomposite seems to work fine.

I'd have to see a screenshot. I feel like this is some sort of bug in a driver or system module, not necessarily obs because it works fine for the majority of people as far as I'm aware.

Unfortunately, I can't take screenshots.

Hey,

Did you manage to solve it, I'm using an AMD R7 240, and not only the screen is not captures but the whole video is blank, at least in recording mode.

Cheers,

Oscar

No, I didn't.

I'm having the same problem. Seems all three of us use AMD. The problem also shows up in other screen recording software. I read on the simple screen recorder website, i think, that a glitch similar to this on their app is due to page flipping being on? Not sure how to disable that through obs if that is the case though. Don't know if the x server flags in the advanced settings of the source properties could disable that through there?

I'd take a screenshot but it doesn't work there either so i guess it really is unrelated to obs.
