Comment # 3 on bug 1213489 from Luciano Santos

OK, I installed ibus-mozc following the wiki article [1] (but I didn't need to
put this in my shell RC file:

> export GTK_IM_MODULE=ibus
> export QT_IM_MODULE=ibus
> export XMODIFIERS=@im=ibus
> ibus-daemon -drx

And everything works just fine for me (as seen in the attachments). But I have
to say, no matter whether legacy applications use "adwaita (default)" theme, or
"adwaita-dark", ibus' pop up window is always dark here.

Another thing worth to mention, I think, is that I'm on Tumbleweed, but I'm on
GNOME:Next too, so I already have 45 alpha/beta releases on my system.

Those are the ibus packages I have installed:

And those are anything Adwaita:
