Odd bug with the software

Currently I have the trial for the software, worked like a charm for the first few minutes but now I get a rather odd bug!

I have two pages, with the function that allows you to drag your mouse from right to left - but the bug I'm having does that I see all of my desktop icons on the other page, and when I hold left click the rest disappears and I see those that actually are there.

The same is for the real page - I see the icons from the other page and when I hold left click they disappear (only when I hold left click)

Also when I double click to disable Fences (or whatever it does), when I hold left click all of my icons disappear (only while I hold left click)

What is this?

Quick edit: the image below only happens if I double click (I think it deactivates the shaded areas), if I disable Fences from the actual menu it doesn't happen

This is what it looks like when Fences is disabled and I hold left click
