In bug 48722, blur had been implemented for shadows (v.7.1), and Draw/Impress have an UI to set it up. But the UI is absent in Writer. This is not only a consistency issue: while one can create such an effect in Draw, copying such an object and pasting in to Writer does not offer the same end effect (see bug 154300: particularly, the pasted object with the blurred shadow would arrive as a Drawing object, and would not allow assigning frame styles).
Using Version: 7.5.1.2 (X86_64) / LibreOffice Community Build ID: fcbaee479e84c6cd81291587d2ee68cba099e129 CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded I drew a circle in Draw, added a shadow, gave it a 6pt shadow with a 5pt blur, copied & pasted the circle into Writer, and did not see a way to modify the blur / shadow from writer's property sidebar. While properties for the object are exposed for shadow & blur under Format --> Text Box and Shape --> Shadow, those properties don't match the values that I set in Draw. Instead, they show use shadow checked, color gray 0% (correct), a blur value of 3 points instead of the draw's 5 points, and a distance expressed as inches in a scrollbar rather than as 6 points as I selected in Draw. I can confirm there is no exposure in the UI at all via the sidebar for an object pasted from draw for Shadow / Blur, and that the values found under Format/Text Box and Shape/Shadow for the object I pasted don't match the original values I selected in Draw. So something's definitely amiss.
In Writer, if you insert a shape, right click - Area - Shadow - we have here Blur.
(In reply to BogdanB from comment #2) > In Writer, if you insert a shape, right click - Area - Shadow - we have here > Blur. That's correct, drawing objects have it. But not available for e.g. Paragraphs or Images. Mike, is the same code used for paragraphs and image shadows? In that case, I think this can be marked as a duplicate of bug 148177.
