Interesting to see there is a way to get it to run under Linux. That the mixer popup and fx closing also closes the program unless in a docked window suggests there may be other things that don't fully work either.
But, if it took you a while to get it this far, well done.
Running any software on unsupported OS's, leaves a user 'on their own' regarding support in case of issues from the forums or the software producer.
Unless anyone else who posts here, has the same system set up, and is using the same software, the probability of getting help from other users in this forum is low.
