Strange keyboard layout switcher behaviour after reboot

I use Alt+Shifl L keys combination to switch keyboard layout. But after reebot it be changed to shift + alt. Literally. I should to press Left Shift then Alt to switch language. Reverse combination (Alt + Shift) don't work. In Text Entry Settings everything looks fine - combination remain.
If I change combination to another, even Alt+Shift to Shift+Alt, switcher work correctly independend of which of keys be pressed first. But only to a next reebot.

This behaviour started about a week ago.
