The height of gkt-entry widgets are very different in gtk2 and gtk3 apps. In gtk3 app is it higher and take to much place.
Can you make it like in gtk2-entrys ? Look at the screenshot.
I think you could make the menu and toolbars narrower.
I found the solution. It is in the file gtk-contained.css:
`
/****
Text Entries *
****/
spinbutton:not(.vertical), entry {
min-height: 28px; <------ THIS IS IT, I changed it to 8px now it is better.
`
I think, Linux lacks a compact theme, all buttons, menu bars and toolbars are too big. Maybe this theme needs a compact version because this theme looking very good and has good usibility.
