Client keyboard input problem on Debian 9

[Particle]

Hello folks. FZ Client appears to have a keyboard input issue on Debian 9. Backspace and delete don't appear to work in most textboxes. I've tried both the version of FZ in the Stretch repository and also the latest version on the FZ website. A fresh install of Debian 9 yields the same result, so I don't think it's just me.

Does anyone know where I might look in order to get to the bottom of the issue? Could there be a missing UX lib? Maybe it doesn't work right with Linux 4.15?

Do you by chance have ibus installed? It interferes with normal keyboard input.

An expert call on your part. Removing ibus and rebooting solved the issue.
