I had the same issue with this last summer: Feature Layer incorrect rendering with webgl rendering and picture marker symbols and it was resolved with 4.9.

A couple of bug reports were filed about it: 

#BUG-000115988 Picture Marker Symbols in Feature Layer are unable to display with WebGL enabled when imageData of the symbol stored at REST Endpoint is lengthy.


#BUG-000115991 Picture marker symbols in FeatureLayer with WebGL enabled display as jumbled when using more than 10 unique value categories to symbolize points.

You may want to open a support ticket with Esri and have them look at this again if you're seeing the same issues because it looks like the exact same thing we were experiencing with 4.8.
