1014980 - Tappy Chicken does not render correctly

Status: RESOLVED INCOMPLETE

(Core :: Graphics: CanvasWebGL, defect)

The new "Tappy Chicken" demo from Unreal,

https://www.unrealengine.com/html5

does not work on one of my machines, but does on the other. On the machine where it fails, it does work on Chrome. These are all linux machines so Chrome is using GL to render (not a software fallback), so it isn't just that my GL drivers are broken - also, all other WebGL demos I've tried work fine here.

What I see when it fails is attached.

I also see the same problem on all other UE4 demos, on my machine, like the Strategy Game. Some textures are either black or not rendered at all.
