Space appears after cursor

Whenever I press spacebar the formatting mark appears after the cursor and the cursor itself doesn’t move. It makes typing so much more annoying. Whenever I add or delete spaces the cursor just stays in place and when I start typing letters it jumps to it’s proper position.

I’ve got Ubuntu 18.10 and LO 6.1.2.1

I’ve discovered that it happens only in the lines where text is aligned center.

Can’t reproduce under Linux Fedora 28 + KDE + LO 6.0.6.2. What is your configuration (OS + LO at least)? Don’t use an answer for that, edit your question.
