I have the same problem Like Nicholas Shatokhin and inferrna , but i noticed that i dont have to reboot , the problem even appears even if you work at the pc as the time goes by..
The shortcut even though it shows "Alt + Shift L" it only works if you press "Shift L + Alt" and the only solution is to reset the text entry to "Alt + Shift L" again .. and again..
