I using OBS 21.1.0 on Ubuntu 18.04 LTS at Twitch stream.
But some game and Windows is Black screen when I capture Xcomposite.
For example, "Mark of the ninja" and "Google chrome" is Black screen. but "Mad Max" "Witcher2" is OK.

OBS logs writen like this.
"glCopyImageSubData failed, glGetError returned 0x502" "device_copy_texture (GL) failed"

I tried re-install but nothing happened.
and I tried terminal command like this.
but nothing happened.

can I fix this problem?
