The size of the folders on the desktop and the upper (gnome?) bar both suddenly changed yesterday.
As you can see in the picture, the text Tweaks
(on the top bar) and example
(on the desktop) are smaller than the font in the file navigator.
I checked this post (How do I change fonts and adjust their size?) but curiously, the values seem unchanged and are still at their default values. (See pic)
Which is the relevant parameter for the upper menu and desktop icon font size?
Thanks!
Going to Settings, then Screen Display and select 'turn on fractional scaling' worked for me.
Note that the actual scaling remained at 100%, but changing that option seemed to make the difference.
No idea what the root problem is, but another thread said a bug has been identified after a recent update: Ubuntu 20.04 interface font too small after restart, even with high scaling factor
