Few years ago I created this issue:
https://github.com/TTimo/GtkRadiant/issues/339
and then it somehow fixed itself(was testing on empty map after getting reply and behavior didn't reproduce because of that). Figured out what is causing enormous size, but have no idea how to reopen old issue so creating new "request" one.
To reproduce:
start radiant with empty/new map
create brush
add any key (e.g. "wad") with very long value, (e.g. "D:\games\Steam\steamapps\common\Quake\Id1\id.wad;D:\games\Steam\steamapps\common\Quake\Id1\dwroae.wad;D:\games\Steam\steamapps\common\Quake\Id1\nehahra.wad")
open Entity Info
you can add similar value to any key of say func_door and then switch to this entity in Entity Info. Window will increase its width roughly to twice the length of value you entered. Now you can't shrink it, only resizing option is to make window larger.
