Ok, i found the solution by myself
- My XIM is not set properly, it should all be fcitx
thus add these in /etc/environment
GTK_IM_MODULE=fcitx
QT_IM_MODULE=fcitx
XMODIFIERS=@im=fcitx
- I don’t why but it seems that gnome has something to do with left CTRL key, when using right CTRL everything is fine, And i found, When point location is on, left ctrl is stuck, thus you can’t use it in minecraft
Just disable it bruh
