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

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?
