Xwayland reports uninitialised gamma values

Running xgamma on a wayland session in gnome-shell 3.36.2 reports invalid and seemingly uninitialised values. Typically -> Red 0.000, Green 0.000, Blue 0.000, but right now I am getting -> Red 0.000, Green 429496.531, Blue 0.000.

These values are out of range per xgamma itself and cause confusion and divisions by zero in programs attempting to read them (e.g. wine).

I don't expect to be able to control gamma correction on a wayland session but would it be possible to report sane values?

I am running on Debian testing.
