Don't switch keyboard layout if fast typing

1. Briefly

Keyboard layout sometimes not switch for me, if I print my texts fast. It would be nice, if my keyboard layout switched each time, when I press Alt+Shift. I will approach any built-in solution or gratis software.

2. Detail

I have Windows 64-bit EN; The problem is reproduced many times in Windows 32-bit. I have 2 keyboard layouts — English and Russian. I switch my keyboard layout use Alt+Shift hotkeys. Sometimes layouts not switched for me, if I print fast. If I print slow, the problem is not reproduced for me.

For example, in a demonstration GIF keyboard layout not switched for me 2 times. In GIF one can see that I correct press Alt+Shift.

Original GIF:

0,07 speed:

The problem reproduced for me in Notepad or any others applications.

3. Did not help

1. I don't find setting in Control Panel\Clock, Language, and Region\Language.
2. I don't find on Internet any possible solutions to this problem.

4. Do not offer

1. Please, do not offer use another shortcuts for switching between keyboard layouts. I don't want it. I used to use Alt+Shift.
2. Yes, I use a program to change words, printing in the wrong keyboard layout —Mahou— but sometimes I need switching between keyboard layouts manually.

Thanks.
