Created attachment 188618 [details] Image with blur shadow Open attached presentation. It has a slide with two images. The images have a shadow with blur. The blur effect is missing in edit mode and in presentation mode. The shadow is solid. I have tested it with Skia on and with Skia off.

Affects more than Impress, and affects more than images. Blurred shadows of shapes, images, fontwork, formulas are affected.

I am seeing white polygons in the LibreoOffice round .svg logo in the About dialog in the patch. It also occurs if you put the .svg in a document so it looks like some extra tweaking is needed. I'll see if I can find something that preserves the fix for this bug without breaking .svg rendering.
