I don't know if it's a bug or a feature taht may be changed in some way, but keeping on playing with the 3.2.1 other strange things appear. Now when a city has few units the icons are normal while when the number of units into a town raises the icons are made smaller and smaller till the point it's impossible to distinguish one from the other. In previous versions there was an horizontal scrolling bar that made all the units accessible now it looks like they're forced to enter the box and teh bar appears only afterwards. I've included a screenshot of a city to show the effect.
I'm using version 3.2.1, gui-gtk-4.0 client.
Is tehre any setting
