can you try it again by disabling paletted images?

      paletted: false

> Hello, we have recently implemented MapProxy authorization with restrictions to polygon. Everything works fine, except that tiles which are intersected by polygon boundary looks different than rest of tiles (see example below). I thing that it is due to image interpolation. My question is: Is there any way how I can change (or disable) interpolation during tile masking?
