Bug description

Hello, I don't know if this is relevant as it is not on Mint, but, I believe, on any other distro. I've personally tested it on CachyOS, Endevour and Fedora. Basically gtk4/libadwaita apps have theming issues:

• the minimize and maximize buttons appear dimmed and do not function;
• the cursor theme doesn't follow the system's - in look and size;
• and the accent color doesn't follow the system's.
  This might not be so on Mint thanks to the patched libadwaita, but other distros don't have that.

Steps to reproduce

Open any libadwaita app on Wayland, on any non-Mint distro.

Expected behavior

The window buttons should function, the mouse should follow the system's theming, the accent color should be closest to the system's. Usually gtk4 apps should follow the gtk3 theme, but that's only implemented on Mint.

Additional information

No response

The non-functioning window buttons should be at least investigated here to see if we can do something about it in muffin.
For the other points: These are theming issues. Mint cannot force other distributions to use the same patchset for a 3rd-party library. File these with the affected distributions.

These theming issues seem to be only Wayland-specific - below I've switched sessions on the same CachyOS installation and you can see the cursor theme applying correctly on X11. Though the accent colors currently are broken there, I think they worked on a fresh install.

• the cursor theme doesn't follow the system's - in look and size;

This problem could also be (and I think it is) related to lack of support for cursor-shape-v1 protocol in Muffin. WIP patches: linuxmint/muffin#756 linuxmint/cinnamon#13156
