Output layering issues

On Ubuntu systems (including derivatives) using the LXDE desktop environment, the output windows for Quelea aren’t layered correctly. From what I have seen, the Video window should be underneath the Projection Window, but that is not the case with LXDE. The Video window is always on top. It seems to put itself on top whenever an item goes live, even when I raise the Projection Window. I have no idea why this happens.

I have seen this happen on three separate machines, one running Ubuntu Studio and the other two running Peppermint OS, all of which are based on Ubuntu.

Quelea is up-to-date with version 2019.1.

Any work arounds for this?
