It seems that after fcd02bd, the backspace and arrow keys no longer work in the TextEdit in native linux. I guess it thinks IME is always enabled? Even if I disable the compose key and use only the physical keys, it still doesn't work.

Yes. I am currently preparing to commit. Do you use IME? or Will it be recognized as IME enabled even in English?

[YgorSouza]

I don't have IME, just a regular US English keyboard. I use the compose key from the Gnome desktop environment, which allows me to enter special characters, e.g., RCtrl + " + E enters the Ë character. I don't know if that counts as IME, but the arrow keys and backspace still don't work if I turn that off in the system settings. The TextEdit gets the IME enabled event as soon as I click on it. It is disabled when I move the window, and the enabled again. If I enter a special character with the compose key, it gets the commit, disabled, and enabled events. So basically it is always enabled while the TextEdit has focus.

Also, when I press the compose key, it adds a · character to the string until I press the other keys, and if I click away the character just stays there.

Yes, that special character input is considered IME.

Please check if there are any problems when applying #4912.

This does fix the problem with the backspace and the arrow keys for me, and the compose key is still working like before.
