Window preview overlay makes the app inusable #137
Description
Hi!
First of, many thanks for providing a way to install Affinity without too much hassle!
I've used the .AppImage for some time, but ended up installing via python as it was crashing too many times.
Everything went well during first use, but now, every time I open the app, I have an window that appears on top of the Affinity window.
It looks like a preview window of my canvas, but I have no way to move it around, nor close it or resize it. And I can't interact with the app in any way in the background.
I have looked in previous Github issues and common issues doc, but haven't found any hint on how to solve this. I changed the rendere from Vulkan to OpenCL, but it didn't help either.
Would you have any idea?
Best,
— Phil
