When I open monolens on OSX 10.15.7 (Catalina) the viewer window always appears to peer through any of the application windows I have open and show only the desktop. For example, in the screenshot below I have a PDF document open in Preview but the monolens window views through it to the desktop image (which I have as the default OSX Catalina one):

or here when I call it using pipx:

I am not sure if this is in any way related to the permissions setup described in the project README,

On OSX, you need to give Monolens permission to make screenshots, which is safe.

I am unsure how to actively give those permissions.

Any ideas?

I'm not entirely surprise, since screenshotting utilities etc. are different under wayland. But from the stacktrace it's not obvious why exactly it crashed and in theory, Qt should be able to handle wayland, or shouldn't it?

Anyway, would be cool if someone else could try it and if they can reproduce it, add it to the limitations in the readme, after all wayland is slowly becoming more mainstream. But maybe just something with my system configuration is broken :man_shrugging:
