Clipboard in Xojo (and Xojo Apps)

The clipboard (Text) is empy after quitting Xojo or Xojo Apps.
Why is that?
In other Apps the text is preserved.

what platform?
I just loaded up Xojo under OSX, copied a chunk of code, exited Xojo, and pasted the code into another app with no problem

I was going to ask if you had something like 1Password running, but then I remembered you’re on Linux.
Not a clue what Linux clipboard manager could be up to.

Yes it’s on Linux.
