Toggling Fullscreen/Windowed doesn't work

[JeddyH]

I don't know if this normal behaviour for this program but it acts weird when you try to change it to windowed mode.
It kinda just flashes the windows task bar and goes back into fullscreen mode.
I can manage to get it into a stable window if I stretch projectM over my 2 screens a few times until it freaks out and changes its rendering resolution to 640x480, then I'm able to toggle it into a window.

The Microsoft Store version runs in a window but has less control, looking for a happy medium between the 2 without have to compile this from source.

I've seen other people here bring this up, seems like an issue tbh.

Anyone figure out how to do this? I'd really like this to run in a window.

The current version here on Steam uses exclusive fullscreen mode, which will change the resolution to something else (normally the initial window size, which is 640x480 AFAIR), so the reported behaviour is correct, but inconvenient.

To reconfigure it, you first need to check if you have the config.inp file[github.com] and create it if it's missing. Then open it in a text editor.

In this file, you can set the fullscreen flag[github.com] and also the initial window size[github.com] which you can use to set the fullscreen resolution.

Currently, I'm rewriting the whole application so it uses the fake/windowed fullscreen mode by default (can be changed via config), not changing the display resolution. Switching between windowed and fullscreen mode has also been improved, as well aas other aspects.

You can find my development pre-releases for free here, on all major desktop platforms:

• https://github.com/kblaschke/frontend-sdl2/releases

There versions are generally more stable than the current Steam version. Note they use a different configuration file format and location. Open "projectMSDL.properties" in a text editor to edit. The file is well commented to get you started. The dev releases also come with a larger preset pack as well.
