Pixel distortion / shifting when using setDepth() about phaser HOT 3 OPEN

seems to only be an issue in WEBGL and not CANVAS, also seems to be an issue with having multiple scenes render, I consolidated your example test code into a single scene (with some minor adjustments) https://jsitor.com/z3lB4A5yWE and can't get it to reproduce afterwards. I'm not versed enough in the webgl renderer to dive much further but hopefully this helps Richard or someone else track this down.

Thanks for taking a look. My original example was born from the project I'm working on that uses two scenes - one for the game world and one for drawing UI objects and handling UI interactions (e.g. dragging game items to your inventory). Although the issue presented itself while using setDepth() and there's at least a temporary fix by setting the UI scene's camera roundPixels property to false, maybe the root issue is more in line with what you've discovered - using webGL and multiple scenes.

I reproduced this with 1 Graphics, 1 Image, and moveUp(): https://phaser.io/sandbox/q89fEzzs
