Hi, I’d like to get your thoughts on what the expected behavior should be when setting the size of a window while it's in a maximized state.
Here are the options I’ve considered: a) Ignore the resize while maximized, and when restored, revert to the size before it was maximized b) Demaximize the window and apply the new size immediately c) Ignore the resize request, but store the values and apply them upon restore If I understood correctly, Martin mentioned that both macOS and Windows apply the resize immediately while keeping the window maximized. Then, when the window is demaximized, it restores the previous (pre-maximized) size, which suggests behavior leaning toward option a. For fullscreen mode, the expected behavior appears to align more with option c, as documented for Stage fullscreen. -- Thiago.
