No, I was referring to the new default behaviour of the hyper key and how it changes how Emacs handles ISO_Level5_Shift:

(put 'none 'modifier-value 0)
(setq x-hyper-keysym 'none)


Previously nil is the default.
But some people couldn't input correctly, so I reverted it to t,
also because I thought t was what the gtk app should be.
See:
https://github.com/masm11/emacs/issues/43

Regarding the behaviour with input methods, I honestly think that this is a bug that should be fixed since it straight up makes working Emacs setups impossible by disabling fcitx support (I have so far been unable to get ddskk working on NixOS).
