Looks relatively easy to fix.

Hm, can it be some race?

Good to hear.

Vincent, what do you think?  Can it be accepted to the upstream and
eventually put into 12.1?

Does GTK_IM_MODULE=scim work at all?  I doubt that the problem remains
from 11.4 unfixed, but no one didn't care (and experience) because
usually scim-bridge is used instead.  Maybe upgrading scim to the
latest version fixes the issue?

This might be the original patch.
The question is whether the code quality is good enough.
