@marcan dang, that sucks. the only thing i might know of that might work is the webamp desktop client, since i know that thing takes up the whole screen (my window closing effect is that classic fire effect, and whenever webamp closes, my whole screen is on fire, meaning that's how it achieves that)
@EeveeEuphoria Yeah, a single transparent window with internal subwindow management is *probably* the way to go on Wayland, though I'm not a Wayland window management expert. It's a tricky problem.
