Device pixel ratio is not setting correctly

Pixi.js is not handling the device pixel ratio correctly that’s why text become blurred
By setting the PIXI.RESOLUTION = 2 seems to solve the problem but there are issues on iphone deices (text and images become extremely blurred) and may be on others.

I have checked the problem thread on GitHub github.com/pixijs/pixi.js/issues/1835.

May be latest version of Gdevelop is not using latest version of pixi.js (3.0.8).
Or there is any cross browser solution to handle that?
