Zorin OS handles modal windows in a very weird way. The modal windows can't be moved independently of the parent window. Here is a demo video of the problem:
This is a problem that was bugging me since Zorin 15.3. I originally thought that this is an issue present in Gnome and it's like this across every Gnome based OS. However, after testing several other distros, I came to the conclusion that Zorin is the only Gnome desktop OS (that I know of) that implements this feature. I'm surprised that no one has ever complained about it.
This is how modals look like on basically every other distro:
I wonder if this was a deliberate choice or not. But regardless, this is something that annoyed me a lot as I couldn't move modal windows out of the way to read a label or something. It disrupted the flow of work and subsequently the productivity.
I will tag @zorink and @AZorin to bring this feedback to their attention.
