Wake-From-Suspend Authentication Fails When Screen Flickers

Whenever I attempt to log in to my qubes os from Suspend Mode, the authentication fails, but only if the screen happens to flicker while I’m entering the password. Otherwise, authentication works fine.

It’s not a high-level issue since all I have to do is re-enter the password again and it works. But it is a bit of an annoyance.

Any ideas on what could be happening?

Thanks!
