PPTX slide with bad gradient colour

Among other problems on this slide the gradient backround is anything but smooth.

So the left pic is MSO I guess

But yeah I confirmed with PPT viewer.

In LibO the gradient area goes beyond the right border of the box. The gradient stops are too abrupt.

And still the same on LO 5.2 nightly 2.3.2016 on Windows 7 SP1 64-bit.
Comment 6 Ari Latvala 2016-03-14 20:59:25 UTC
And also the latest LO 5.1.1.3 on Windows 7 SP1 64-bit shows really ugly gradients on show mode.
Comment 7 Ari Latvala 2016-06-02 20:22:27 UTC
Problem still there on the latest LO 5.2 Beta 1 for Windows 7 SP1 64-bit, especially on presentation mode.
Comment 8 Ari Latvala 2017-05-29 20:35:31 UTC
Still no change to this on LO 5.3.3, having these two gradient fills lapping each other and higher but narrower having frame with gradient color on the original file looks just really awful on Impress, when compared to MS PowerPoint. Both the animation and endresult are just unacceptable.

Tested with the latest LO version. On slideshow animation is still not smooth like on MSO.

Looks fine to me in 7.6+, but I'm not a fussy artsy type.
Comment 15 Piotr 2023-06-04 18:46:31 UTC
I checked it, my slide looks similar to the left photo in the attachments. So I think there is no bug. Version I tested with:

Version: 7.6.0.0.alpha1+ (x86) / LibreOffice Community

Comment 16 Ari Latvala 2023-06-05 06:30:11 UTC
Version: 7.5.3.2 (X86_64) / LibreOffice Community
Build ID: 9f56dff12ba03b9acd7730a5a481eea045e468f3

Just checked and with LO 7.5.3 the end result regarding fill gradients colors seems to match MS Office but the LO version of the animation is still really bad, hard to call it animation when compared to MS Office.

Attached videos of LO and MSO versions of gradient animation. Huge difference.
