Created attachment 162242 [details] Two sample slides (PPTX) Both of these two slides exhibit the same issue. The transition "softening" the image is quite off in Impress compared to Office 365. (I believe the gradient angle is off by 180° and also the position of the gradient looks different in LO than in 365, but that is just a preliminary diagnoses - the issue is ... it looks very differently.)
