I see similar behavior. > I came up with the attached patch that solves the issue for me.

I tested the patch and can reproduce your findings. The first paste now works. As you mentioned, I still get the warning, but only one warning where without the patch I get three warnings. I tried a few random variations on your patch to squash the last warning. One that worked for me is to add return true; after xcb_flush(con); I have no idea if that makes any sense but perhaps it provides a clue. Does the warning go away if you add that? Finally, this doesn't seem to solve the flood of messages I get when CopyQ is running, but I don't think this is worth investigating. Scott
