Bug Description

I'm running 14.04 Beta with daily updates. I've got English (US) and Russian layouts, source switching is set to Caps Lock. However, if i'm typing fast I often have my input switched to CAPS mode instead of changing layout. Looks like that:

I don't know which package is responsible for this bug and what can I do to investigate it.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

I've installed Ubuntu on 2014-03-18 (I believe it was daily build from 2014-03-17, was updated during installation), but barely used it that day, and I've noticed the issue on 2014-03-19, so I think it was there from the beginning.

Has the same behaviour on current (released) version (after update from 13.10).

And sometimes CapsLock works like Shift, with or without layout change.

To ensure the switch I have to wait a couple of seconds after releasing the key, which annoys very much if you used to type fast.

Работающий костыль. Чтобы переключатель раскладки CAPS LOCK работал нормально, приходиться ставить пакет gnome-tweak-tool и в нем в разделе "Клавиатура" пункт "Поведение клавиши CAPS LOCK" ставить в состояние "CAPS LOCK отключен". После этого включаем CAPS LOCK как переключатель раскладки. Ubuntu 14.10
