[hyprbars] bar background gets transparent when window is hovering newest ghostty window

[kthu]

A bit hard to put into words, so I made this video clip to demonstrate:

If I have several floating windows, this only happens with the one that had focus the longest time ago. Only the part of the ghostty window that has some transparency shines through. If I run a TUI app with opaque background, only a thin border shines through.

I started seing this behavior with Hyprland 0.55.

Update: Its not only Ghostty. I also see this with other windows that has a background with some degree of transparency. Tested now with Emacs and Foot.
