Camera Shake pixilation isssue

I'm having an interesting issue where when I use the Camera Shake FX on a .png image, the timeline playback seems normal, but upon rendering, the image with the effect is pixelated! Im not sure why this happens/if its a bug? Is this a known issue? I should note that the effect is applied to the image itself, and not an adjustment clip.. I am going to test this theory out now, but i thought id leave a heads up!

I couldn't duplicate this in Studio 17b6 for Windows. The image looked great.

What I did see was black around the edges of the image that should not have been there. It looks like the effect is using only the timeline raster and not the entire clip raster.

Whether bug or design flaw, it needs correction.
