I have two languages as input sources: us, ru.
By default there is only Win+Space keyboard shortcut to switch between them.
When I enable only LAlt + LShift shortcut with Tweaks:
the shortcut starts to work as expected, but along with it I have RShift + LShift enabled, which also switches languages in the same way. It is very annoying, as when typing fast it switches unintentionally two times per minute.
Is there any way to enable the only LAlt + LShift to switch it?
