Devilutionx: Cant resize window after toggeling full screen

[AJenbo]

When switching from full screen to window mod with alt+enter it's not possible to resize the window even when upscaling is enabled.

[arrowgent]

is that because the resolution of the window is 640x480
is it a SDL issue?

[AJenbo]

No, it is simply because we do not set the SDL_WINDOW_RESIZABLE when starting the game in fullscreen mode:

Should be simple to fix.

@AJenbo in this case, it would solve it?

    if (fullscreen) {
        flag |= SDL_WINDOW_FULLSCREEN_DESKTOP;
    }
    flags |= SDL_WINDOW_RESIZABLE;
