In the stations info the input field ( name from station ) ignored gui_edit_height.
should be fixed with r8217
r8224 not work
not work in other windows Savegame Load, Vehicle Info, Depot ( input Filter ) and City Info
I cannot reproduce this, it works for me: I checked by setting gui_edit_height to 34, which is large. The input fields you mentioned were of correct size.
The input fields like in the line selector in the depot window are not affected by this setting, but by button height.
For me under Windows 10 - 1703 does not work in r8224.
r8214 works as v120.2.2
here to compare r8224 and v120.2.2 - Theme "Simutrans (large size)" and pak64
