Hello!
I'm using latest Zen on Windows 11 23h2 with mica installed.
Today all was fine until I toggle this setting "zen.view.grey-out-inactive-windows"
So now even if I retoggle it several times, several PC reboots, Mica uninstalled, All CSS and mods was removed, new profile was created but it's still greyed when window inactive and moreover now my Zen window is completely greyed if I maximize the window.
So in window mode I have nice blur+transparency but if window is maximized my interface is completely greyed.
There is some video:

This issue relative to this thread on Reddit: https://www.reddit.com/r/zen_browser/comments/1k0mhrf/transparent_is_gone_in_full_screen/
My transparency is gone for maximized window also and there is some workaround in comments.
This issue can be fixed until next ZenBrowser restart by pressing F11 twice to go to Windows Fullscreen mode and go back to Windowed mode.
After this everything is fine but until browser restarts. So every time I open my Browser I need to press F11 twice to fix this issue temporary,

This is done by windows, as we are using their native window backdrop material. We cant control it unless you use some third party app, sorry

Why are you using mica for everyone?
