I have a specific issue with RenderTextures in a FragmentFilter.
And I'm aware that internally, RenderTextures are used in the FragmentFilter for however many passes you instantiated the filter to use, but this is different.
I create a separate RenderTexture to draw a dynamic DisplacementMap (it's basically a paint app) and it also serves as a "shadow".
So the issue is, as I resize the viewport (I re-assign the Starling.current.viewPort on stage resize), it doesn't seem to scale the Filter properly.
And there's this horribly huge scale shift happening at certain given dimensions.
See attached GIF, this one shows quite a scale shift as it's resized smaller:
Is this a mipmap issue? On the RenderTexture?
I'm not really sure what to make of this, any help would be appreciated!
