Coverart - Treatment Artifacts

[PenkethBoy 2063]

I think since the move to the new SKIA image processor i have been getting artifacts when applying the Rounded treatment

 

I have applied it to Seasons and episodes - both exhibit the problem

 

e.g.

 

I have highlighted some artifacts in the above image.

 

Its not the end of the world but would clean up the interface for me if this could be corrected.

 

Thanks
