how to disable the wayland detect warn?

[DreamMaoMao]

when I set the var to fcitx, I will receive this warn,it work normally
GTK_IM_MODULE=fcitx

and when I set the var to wayland
GTK_IM_MODULE=wayland,many app which is based on electron will crash.

so I just want to set var to fcitx but don't give me this warn.

how can i do this?
