I made some themes for sway with a script: https://github.com/indicozy/sway-dotfiles-script

And only on a MacOSBigSur theme, there is an issue with managing containers, image explains itself:

I checked it with every other theme and it worked fine. This issue is created only in this specific config. I will test that on my Linux Virtual Machine and will report any issue later.

How to replicate: Just download my script (or MacOSBigSur config) and try it yourself
