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 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.
