Budgie desktop lock screen can't switch language

[ominds]

Not sure if I got the right repo. I installed Antegros with budgie desktop (actually it was KDE first I think, then I installed budgie desktop and removed KDE). I have two languages setup. When I lock my screen, if I'm on the wrong language, super-space doesn't work to switch the language.

My other option is to click the language indicator on the lock screen. If I click it, it flickers, changes language and then back again instantly. So there's no way for me to switch language to English and enter my password to unlock the screen.

My only other alternative is "switch users" on the lock screen, this used to crash until about a week ago (it's working fine now). So it's currently my only option to get back to my desktop.

OK, so I found this issue that looks exactly like my problem
