When building from source, shaders aren't visible to greetd-mini-wl-greeter, so executing it from anywhere other than the directory including the shaders leads to a crash with the following error:
[ERROR]: Failed to load shader shaders/vert.vert: No such file or directory.
This is surely unintended behavior, as the AUR installation works perfectly (used Toolbox to test).
So I read the PKGBUILD of the AUR package, and changed the build type to release, and everything is now working perfectly. I don't know if in debug build type this is intended behavior or not.
