Are you facing a problem where Animation Composer interface is too small or big?
Please let us know. We're investigating what triggers the issue and hopefully we can fix it in next update.
Here is a possible solution:
Please change the settings inside Windows Display to 100% and open up a console inside After Effects by pressing:
Ctrl + F12
This will open a console window where you need to change the view from burger menu to Debug Database View:
In the Debug Database View you need to look for the AdobeCleanFontSize parameter and change it from default to size which will suite you.
