Why does fullscreening chromium disable this on hyprland?

I'm using the ctm backend, nothing else seems to do this

I will definitely look into this later today when I do my comprehensive testing before releasing v0.11.0 soon. This seems real strange.

So I looked into this. It appears this is a Hyprland issue with their protocol. If you use hyprsunset directly, this issue also occurs. I've tested with sunsetr using both the Hyprland CTM backend and the hyprsunset backend (manages hyprsunset) and both have this exact issue. This tells me that this is likely happening at the compositor level and its interaction with Chromium since it responds the same way to both CTM managers, ours, and theirs.

I won't be able to fix this, but if you open up an issue on Hyprland directly, they will likely find a fix for this faster than I ever could. Right now what I could recommend is to try your luck with Firefox, Librewolf, or Brave maybe. Please let me know if you figure anything out that fixes this issue.

So I just realized... You could also just switch to using the Wayland backend. This uses wlr-gamma-control-v1 which is a general protocol rather than the Hyprland specific one hyprsunset uses. The fullscreening works great on my build.
