Can you please attach the CSS you're using as well as your config(if you have one) and the command line options you're using. I and others I know use custom CSS as that's one of the main features and no one I know has seen this so I need more to go on.
Also, next time could you please put this in a code block. The numbers in front of every line caused sr.ht to reference every single issue in this bug tracker.
As cloud pointed out you cannot use wlrobs under gnome. wlrobs does screen capture using the wlr-screecopy protocol which mutter, the gnome compositor, does not implement. Without support for that protocol the only change I could make to remedy this would be to print a nice pretty error message and make the plugin return black frames as a no op so that it doesn't crash OBS. Making the plugin work under gnome currently isn't possible.
