Created attachment 166695 [details] Sample slide (PPTX) I've been looking through all open bugs referring to "gradient", and couldn't find one that fit? The attached slide (PPTX) has several rectangles filled with gradients, alternating left to right / right to left which show in Office 365. In LibreOffice, all those rectangles appear filled with a solid color. Version: 7.1.0.0.alpha0+ Build ID: 86d4419c6c4961c8b473decccea99338c176ffe1 CPU threads: 8; OS: Linux 5.8; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:master, Time: 2020-10-21_08:38:05 Calc: threaded ...but also seen with 6.4.8, so no (recent) regression.

Actually the shapes have gradient fill, but they're hardly visible. The primary reason is probably that MSO can handle gradients with several steps, while LO can only handle a start and an end color, probably conerting that during import is off in this case. Confirmed with LO 7.1.0.0.alpha0+ (f1d798151048dde3f48b124ef406416668d1e9c5), 3.3.0 / Ubuntu. It looks different before 4.4, and it looks reasonably fine in 3.4.0.1 and 3.3.0. The change between 4.3 and 4.4 could be bibisected using repo bibisect-44max to the following commit. https://cgit.freedesktop.org/libreoffice/core/commit/?id=f4a2f1e647354efb75be8c90384d6cd3e5f9b9bd author Tor Lillqvist <tml@collabora.com> 2014-07-14 20:23:22 +0300 committer Tor Lillqvist <tml@collabora.com> 2014-07-16 18:21:27 +0300 "bnc#862510: Improve handling of OOXML gradients" The change between 3.4 and 3.5 could be bibisected using repo bibisect-43all to the following range, out of which a particular commit is dealing with importing gradients from OOXML formats. https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=d6cde02dbce8c28c6af836e2dc1120f8a6ef9932..d419bfc9f7e6114af7461fab17dc0782397e5433 https://cgit.freedesktop.org/libreoffice/core/commit/?id=68e756de2ec7f9aeb1b6a6a28468745eca114715 author Muthu Subramanian <sumuthu@novell.com> 2011-08-23 12:44:51 +0530 committer Muthu Subramanian <sumuthu@novell.com> 2011-08-23 12:48:52 +0530 n#657896 - Gradient Transparencies and Muticolor Gradient fills.

This is just multi-step gradient in a shape not being supported. *** This bug has been marked as a duplicate of bug 76682 ***
