I write in Spanish and sometimes I use diacritics (ie multi-byte chars) with dead keys, for example "liberación" ("liberation" in Spanish). Usually I don't have any problem, but when the GUI freeze or for any reason it can't handle more input, when the text shows up the diacritic char jump to the first position on the/a keyboard buffer, displaying something like "óliberacin", which is very annoying since occur very often while chatting or writing an email (easier to test: aaaá→áaaa). GNOME/Unity/Hardware couldn't be. Maybe a xserver or libinput or a kernel bug?
I have this problem since more than four years now, with several kernels, Ubuntu versions, hardware and versions of Firfeox and Chorme. I couldn't find any pattern neither something strange on dmesg/journalctl//var/log files...
Setup: This happened to me since Ubuntu 16.04 LTS fresh install, kernel 4.4.0-62-generic; and even recently with 18.04 and 4.15.0-134-generic, GNOME Shell 3.28.4.

How can I debug to find where the problem might be?

I didn't cross with this issue for a while, until today, typing from Desktop to Android (GSconnect → KDE Connect Keyboard). The lagginess due to the info sent to the phone make the UI stall. This could be a good way to reproduce the issue.
