I've been able to replicate the issue in GNOME on Wayland (works fine in X). Unfortunately I don't think there's much I can do about it, since I can't seem to find any color picker that actually works in Wayland. From this article: https://lwn.net/Articles/607091/ it sound like Wayland prevents applications from getting any pixel information from the screen (for security reasons). As far as I can tell, this pretty much prevents any attempt at implementing a color picker in Wayland.

OK, thanks! Maybe I should turn to X from Wayland.
