Map overlay drifts off screen

Clicking tab to show the map overlay and it starts to drift off screen
Clicking tab again resets it's position, but stuck in overlay mode.

My guess is some input is being sent, because when alt-tabbing away, the map overlay stops drifting.

I uploaded a video example to youtube: https://youtu.be/4fPHqnssLJI

Thank you for making a great game <3
