Hi, I just installed P3 on my desktop, which has two monitors, when running a sketch, my own or an example, the sketch is displayed larger than full screen, I can’t even view the content.

Processing 2 works fine.

Why is it doing this and what is the fix? I didn’t see any solutions when searching

OSX 10.11.6

Just the regular `size(600,400);`

Adding `P2D` doesn’t change anything, still goes full screen

I am sorry, I am not familiar with OS X.

In Win I’d say update your graphics driver.

Did you try `size(600,400,JAVA2D);`

Same issue, I’ll try on my laptop and see if it’s related to this one machine.

can you toggle between full size mode of a window and normal size mode?

There is something like this in Windows

Try disconnecting the second monitor and see what happens. Also goto System Preferences and look at the settings for your dual screen setup, it might be it is trying to use both monitors as a continuous desktop,

I’m having this same issue. I’m running a very basic program with the window size specified as 400x120 and when I run the sketch, it opens a window that spans the full resolution of both of my monitors. This is the basic sketch I’m running:

void setup() {  
size(400, 120);  
}

void draw() {  
if (mousePressed) {  
fill(0);  
} else {  
fill(255);  
}  
ellipse(mouseX, mouseY, 80, 80);  
}

I tried the suggestions previously mentioned and none of them worked. Has anyone found a solution to this?

ok found a weird way to fix it. 🙂  
remove the size command and run any sketch. it will default to 100,100  
then add a size command and rerun the sketch… bingo now it sizes the windows to all the sketches run after this
