I really like Pop!_OS' tiling feature but the one thing that really bugs me is you can't disable windows always raising on hover. You're meant to be able to tweak it using Gnome Tweaks however disabling the option and enabling tiling means flinging your mousing anywhere causes all the windows in its track to raise to the front. If you've got a floating window it just disappears behind the stack.
Theres an open issue[1] but it hasn't been solved yet.
