Hi!
It looks like right Alt+Shift for keyboard layout doesn't work because right Alt binded to russian rouble sign ₽. So I can't use it to change between Russian and English.
it is same on Windows 10.
I need right Alt+Shift behaviour because I long time used it on Windows 7 and KDE4. Now it doesn't work and other variants are comfortless for me

Works fine with English/Kazakh layout. So, good bye Russian
