Keep in mind, currently the library cannot be set globally, if you use GTK3 applications, it will break them.
The recommended usage right now is making scripts in ~/.local/bin/, with the same name as the original GTK4/libadwaita application, and use LD_PRELOAD on them individually.
There is an open issue for fixing this: https://codeberg.org/MorsMortium/GTK4-NoCSD/issues/3

It depends on libadwaita, which itself depends on gtk4. For the second part, that might be something that all distros could use, so I think I will make an issue in the repo.

This should depend on gtk4.

Also, suggestion: To add example files (under /usr/share/doc/gtk4-nocsd/examples/profile.d/) for a /etc/profile.d/gtk4-nocsd.sh and a /etc/profile.d/gtk4-nocsd.csh.

Regards and thanks for that package!

@morsmortium Thank you builds for me now as well.

Alright, I thought this was some GPU-less setup where wlroots still wanted a GPU accelerated renderer, but that was not the case. I tested building in a clean chroot, and this was the XDG_RUNTIME_DIR issue again, since I had to move it into the build script. I have fixed it

@morsmortium Thanks and I'm getting the same results...
Did the PKGBUILD need updated to pull in your changes?

Thank you for the report @Cody_Learner This seems to be a wlroots issue, but I tried to make a workaround with replacing the default hardware renderer with software. Can you retry it?

@morsmortium

I'm having issues building the 2025-09-25 update in a clean chroot.
