Zoom window is too small on Ubuntu 20.04 with a 4K screen resolution and 200% scaling

I'm running Ubuntu 20.04 on a 4K screen with 200% scaling, and when I run Zoom, the menus and texts are simply too small. All other applications are scaling as expected.

I've attached an print screen with Zoom open, and with the terminal output.

Does anyone knows how to work around this while retaining the 4K res?

Solution 1:

Zoom currently creates a file named zoomus.conf under your .config folder in the user's home folder.

One of the settings is ScaleFactor, set to 1 by default. Set this to 2, and next time you start the application it will have appropriate-sized visuals.

Solution 2:

In my case, it helped to go to .config/zoomus.conf and set

autoScale=true
