Keyboard input don't work

I’m using Ubuntu 15.04, I’ve got two keyboard layout configured: “en” and “ru”.
When I launch UnrealEditor with “ru” layout active, keyboard input doesn’t work in play mode even if I change layout to “en”. Keyboard input doesn’t work only in play mode, I am still able to edit blueprints etc.
When I launch UnrealEditor with “en” layout active, keyboard input work fine in play mode.
P.S. Sorry for bad English skill.
