Description

When running a sketch in fullscreen mode, pressing escape key does'nt always close window at first attempt.

Expected Behavior

Always close sketch window at first escape key press

Current Behavior

About 50% of the times I run the sketch, escape key do not close sketch window.
After doing a left clic on the screen, and then pressing escape key does correctly close the window.

Steps to Reproduce

void setup() {
  
  cursor(CROSS);
  strokeWeight(0);
  fullScreen();
}

void draw() {
  
  background(240);
  
  fill(255);
  rect(0, 0, width, height);
  
  fill(0xff777777);
  textAlign(CENTER, CENTER);
  textSize(32);
  text(mouseX + ", " + mouseY, width/2, height/2);
}

Not sure there's much we can do here… If it responds after a click, that means the window didn't have focus. We can only request focus (which we do, and which is why it works most of the time) but it's up to the OS whether the window is focused or not.

I saw that in How to Use the Focus Subsystem
"Exactly how a window gains the focus depends on the windowing system. There is no foolproof way, across all platforms, to ensure that a window gains the focus. On some operating systems, such as Microsoft Windows, the front window usually becomes the focused window. In these cases, the Window.toFront method moves the window to the front, thereby giving it the focus. However, on other operating systems, such as Solaris™ Operating System, the window manager may choose the focused window based on cursor position, and in these cases the behavior of the Window.toFront method is different."

I'm running on Windows. If Window.toFront method is already called in FullScreen mode, seems there is no much more that can be done as you said...
