I have a UI Canvas in “Overlay” mode with “Scale With Screen Size” set and 1920 by 1080 ref resolution. I am using “Shrink” for my screen match mode. Everything looks perfect in the editor game window. I can drag to any shape and the canvas keeps its aspect and Unity puts letterbox type black rectangles where it needs to when the aspect gets too funky.
When I make a build for a windows resizable window however … and resize the window … the scaling of all my elements is all over the place and looks horrible. Should a resizable window perform like the game window in the editor does? Am I missing something?
