I've managed to devise a workaround for this problem. It involves loading a 1x1 pixel FlxSprite, resizing it that based on the line dimensions and then stamping in on to graphic.

Based on this post here, there may be a performance increase on mobile in using this approach.

Recently I updated my version of HaxeFlixel along with several related dependencies. After the update I have noticed the lines I'm drawing through FlxSpriteUtil::drawLine are now blurry on the Windows, Mac and HTML variants of my game. The lines still appear sharp in the Flash variant.

I've adjusted the line style properties I'm using and stage quality but nothing has resolved the issue.

Any suggestions would be greatly appreciated.

Current Result

Thanks! Works a treat.

I'm currently assessing HaxeFlixel to see if it's suitable for a new project I'm working on.

I need to support zooming in/out of a particular scene. I've attempted to do this via a tween on the camera but I always get a shaky result. Any thoughts on how to resolve this?

I've simply added the following code to several of the samples.
FlxTween.tween(FlxG.camera, { zoom: 2 }, 20);
