top line prevents real full screen

[ousia]

Describe the bug

Open the attached SWF sample, that contains the following AS2 code:

if (Stage.displayState == "normal") {
    Stage.displayState = "fullScreen";
}
newloader._x= (Stage.width-newloader._width)/2;
newloader._y= (Stage.height-newloader._height)/2;
load_text=Stage.width + ":" + Stage.height;

Ruffle displays this (reducing both width and height of the full screen):

Expected behavior

FP displays at complete full screen:

I think the --no-gui and --letterbox command line options can help with this.

Many thanks for your ultra-fast reply, @torokati44.

BTW, doesn’t full screen imply no GUI (options beside)?

[torokati44]

Hm, I wouldn't say so... Do you think it should?

[ousia]

I think it should.

After all, (I would say) this is what full screen is all about.

Or what do you get in a web browser or PDF viewer in full screen display?

[ousia]

I have the following PDF document.

This is how Firefox (PDF.js) displays it in full screen (or presentation mode):

The same happens with Evince:

Sorry, @torokati44, but I’d rather say that full screen should have --no-gui by default.

Many thanks for your help.
