Bug Report Black Screen in 2019 (Version 23.1, Linux Mint 19.0, GTX 940M and GTX 1060)


New Member
I've been looking at making some dev streams using OBS, but I haven't been having much luck. I tried on my laptop which is an Acer Aspire with a builtin GEFORCE 940M, and on my desktop which is a TS140 with a GTX 1060. Both computers run Linux Mint 19.0, have up to date Nvidia drivers (390 in this case). I don't own any computers with Windows.

glCopyImageSubData failed, glGetError returned 0x502
error is persistent in both logs. It makes up the majority of the log file.

I've attached the 2 log files below. Let me know if you need any more information. Thanks

Edit: The solutions on https://obsproject.com/forum/threads/solved-window-capture-black-screen.47082/ didn't help me

So I checked the sources I was using, and figured out a workaround. The Window Capture (Xcomposite) source isn't working when in desktop mode. Using Screen Capture (XSHM) does work how ever.
