Created attachment 186047 [details] examples of circular gradient plus screenshot Open attached odt document and save it to docx. Open the document in Word. The outer circle of the gradient area has wrong position. (MS Office uses a quadratic color interpolation in this case. If you change the gradient stop position from 0 to 1 in the file markup, MS Office will use the same linear color interpolation as LO. MS Office uses linear color interpolation also if a third gradient stop exists. So doubling the first color stop forces linear color interpolation as well. Such could be done on export, but would be a different problem.)
Created attachment 186048 [details] manually added tileRect Here I have added the tileRect element manually in the markup. Opening that file in Word shows, that it fixes the export problem. In addition, I have changed pos 0 to 1 to force linear color interpolation. That makes it easier to compare the rendering with the screenshots.
