Image pixelated/blurry after full screen

cocos2d-x JavaScript
#1

Hi guys, I hope someone could help me out with this one.
If I change to full-screen on an android mobile (chrome) when is still preloading everything is fine, but if a change to full-screen after the cc.director.runScene() finishes, everything look blurry/pixelated.

I’m setting full-screen on my game using swiping up in the browser and cc.screen.requestFullScreen() and in both cases, I’ve got the same result

tested: Cocos2d-JS v3.16 and v3.17
device: lg g7
browser: chrome
ani ideas?

//cc.view.enableRetina(cc.sys.os === cc.sys.OS_IOS || cc.sys.os === cc.sys.OS_OSX);// whys this???
cc.view.enableRetina(!(cc.view.getDevicePixelRatio()<0));

that made it work!!!
