Short description of error
AltGr is detected as Right Control+Right Alt, so shortcuts with Right_Alt dont work properly eg. Right Alt+m

Longer description with debugevents
single pressing AltGr with --debug-events:

If i press AltGr, and then click on Ctrl it is detecting just Alt

"Keyboard Test Utility" program correctly recognizes rightalt alone

If i register shortcut via python to Right_alt it is working on release

I don't know if this is hardware specific or windows 10 1903 update issue.
