PgAdmin 3 @ Ubuntu 14.10: low responsiveness when typing

I've been using PostgreSQL and PgAdmin 3 for years without problems so far. Recently I installed Ubuntu 14.10 at new notebook with PgAdmin. The problem is that I have to type very slowly to get the query I want. E.g. if I type "select * from users;" too fast, I get something like "slct* ro srs;". (Each time it's different, of course.) This is very annoying and I'm really stuck with that. Searching on the Internet didn't reveal anything, I don't even know how to debug this.

I'm using Ubuntu 14.10 (everything updated) 64 bit with 16 GB RAM, SSD and Unity. Any solution or debugging hints will be appreciated.

I can't add a comment to your question and my previous answer was deleted.

I just filled a bug (and copied some of your question) about this: low responsiveness when typing

by Robert TheSim

Maybe it is a wxWidgets / iBus bug. I fixed it disabling IBus. Go to Language Support and change 'Keyboard input system' from 'IBus' to 'None'. Not only I don't experience missing keystrokes anymore, I feel pgAdmin is more responsive globally.

then logoff your unity/ubuntu session and logon again.
