Fullscreen + Camera not working in Chrome 80 on Windows 10

[bisalwa]

Up until chrome 79 on Windows 10, fullscreen + camera recording was working fine. However, in Chrome 80 which was released a couple of days ago, after initiating a Fullscreen + Camera recording on Chrome seems to hang and clicking on the badge (or on Stop Sharing) does not stop the recording.
On Mac with Chrome 80, there seems to be a delay on updating the time on the badge and a bit of a lag, however, the recording does stop.

Also, other options (including recording with Chrome tab and camera, just desktop, desktop and microphone) seem to work fine. It is just the full screen with camera is not working.

Update...changing

    constraints.video.mandatory.maxWidth = 3840;
    constraints.video.mandatory.maxHeight = 2160;

    constraints.video.mandatory.minWidth = 3840;
    constraints.video.mandatory.minHeight = 2160;

to

    constraints.video.mandatory.maxWidth = 1920;
    constraints.video.mandatory.maxHeight = 1080;

    constraints.video.mandatory.minWidth = 1920;
    constraints.video.mandatory.minHeight = 1080;

in

background.desktopCapture.js

seems to have mitigated the issue for now.
