Why does VLC ignore --width, --height, and seemingly any other command line options I feed it?

VLC always opens with a gigantic window which is very annoying. So I want to make it open a small window. Reading the documentation at https://wiki.videolan.org/Documentation:Command_line/#Video_options , I found this:

--width, --height <integer> sets the video window dimensions. By default, the video window size will be adjusted to match the video dimensions.

So I used them:

vlc.exe "D:\videos\clown_jumping_on_trampoline.mp4" --width 320 --height 240

VLC opens up, playing that video file in a gigantic window. It's nowhere near 320 x 240 pixels. I've also tried much smaller numbers -- same gigantic window.

In the past, I've tried to use other options for setting the volume and other things. All have been ignored by VLC.

Does VLC even have support for any of its options that are documented? It seems like they are ignored.

No other software behaves like this, so it cannot be "my fault". For example, the media player MPC-HC respects all of the arguments I send to it. (But it cannot be used for what I need VLC for, so I cannot use it for this.)

As the person commented, I have also tried with:

 --width="320" --height="240"

And:

--width="320"

No difference. It's entirely ignored.
