Steps to reproduce the problem:
1. Download "Quake" from the Chrome Web Store
2. Either press ALT + ENTER or click on "Toggle Fullscreen"
3. Sample of fullscreen function:

function toggleFullScreen() {
  if (!document.webkitIsFullScreen) {
      document.getElementById('sdlquake').webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);		
	    if (screen.width == 1366 && screen.height == 768) {
		  if (document.getElementById('aspectratio').checked == true) {
			document.getElementById('sdlquake').style.webkitTransform = "scale(1.3, 1.2)"; //4:3 Aspect Ratio
		  } else {
		    document.getElementById('sdlquake').style.webkitTransform = "scale(1.7, 1.2)"; //Scale 1366x768
		  }
	    }
      } else {
          if (document.webkitExitFullscreen) {
              document.webkitExitFullscreen();
              document.getElementById('sdlquake').style.webkitTransform = "none"; //Scale Windowed
          }
      }
};

Tested this issue on Windows 10 on the reported version 69.0.3497.81 and the latest Canary 71.0.3547.0 by following the below steps.

1. Launched Chrome and added 'Quake III FP-Shooter' from chrome://apps.
2. On clicking on the Extension icon, nothing is happening and unable to see the 'Play' button.
Attached is the screen shot for reference.

I'm also developing "Chrome Packaged Apps" from the machine reported but essentially as you may know for the Chrome OS platform.

My apps used to go fullscreen by the toggleFullScreen(); function pointed above... Everything worked as a charm 'till version R68 on Windows and of course on Chrome OS.

Since the standalone browser is way ahead than Chrome OS in its releases i noted that this function doesn't work anymore at least on Windows/Linux.

I'm also having issues on compiling latest version of Chrome OS and test if the behavior is the same even thought it'd prolly be.


"Quake III FP-Shooter" isn't an app I'm personally developing rather than "Quake" as a "Chrome Packaged App" you may find on the Google Chrome OS platform only.

Please test this one instead.

I've also attached a screenshoot pointing out that Webkit/Blink doesn't transform (Scale, Translate, Rotate) anymore... (Screenshot taken by NESticle for Chrome OS which works fullscreen with the same script).

Since I don't have other code to test if this is the case for other elements but just the "NaCl embed" I'm guessing this should be the only one impacted.

Please Fix.

I've noticed that transform (Scale, Translate, Rotate, etc.) works if "webkitRequestFullscreen" isn't invoked so by the way Blink transform operates correctly on a NaCl embed if not fullscreen... Hope this helps!

5anty83.as@ Thanks for the update.

As per comment #8, this issue seems to be related to Chrome OS. Hence adding the OS as Chrome and requesting the appropriate team to look into the issue and help in further triaging.

Thanks..

The NextAction date has arrived: 2018-09-24

As of today I've succeded to compile my own version of CrOS R69 and the bug seems to be present there too.

Issuing the command:
console.log(document.getElementById('snes9x').style.webkitTransform);

produces the following output:
scale(2.66797, 1.45607)

So the browser is aware of the command issued but doesn't stretch the content.

As pointed out before this seems to work if "webkitRequestFullscreen" isn't invoked but only for the first time after the window is created.

Please keep me up to date!
