The problem with Emacs 27 has already been fixed in 28.  So the real bug
is with the candidiate area blinking.

Other programs such as Firefox typically use the GTK input module, while
Emacs uses XIM, which doesn't like it when the IM server restarts.

Does that only happen under Xwayland?  If so, set
`x-gtk-use-native-input' to t, which will let Emacs use the GTK input
module instead, and should resolve the issue.

Thanks.
