Bug#1004363: ibus: pops up window with accent mark

[Gunnar Hjalmarsson <gunnarhj@debian.org>]

@Brian: Thanks for additional info.

I probably tested on Wayland. Now I have tested on Xorg too, and don't 
see it there either.

I have one idea (and this is a long shot): Do you possibly have an 
~/.XCompose file? If you have, can you try to rename it (in order to 
disable it), relogin, and try again. The reason I ask is that I have 
<https://launchpad.net/bugs/1849399> in mind. It shows that a mistake in 
~/.XCompose might lead to unexpected behavior.

@Osamu: Unloading ibus somehow would only be a workaround, right? I 
mean, you should be able to use a Compose key without issues also when 
the ibus-daemon is running.
