Example file from PowerPoint

Attached user-made presentation has a circle shape on its master slide.
Impress opens it with shadowing set, but it has no shadow set in PP.

Steps to reproduce:
    1. Open attached document

Actual results:
Dark circle is visible on the right side of the slide.

Expected results:
The circle shape should be transparent.

LibreOffice details:
Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: 6b3f0866e9eddd5553857741862ca0d7d5b2ec2b
CPU threads: 4; OS: Windows 10.0 Build 18363; UI render: Skia/Raster; VCL: win
Locale: en-US (hu_HU); UI: en-US
Calc: CL

In 7.1 the problem became very visible, but the extra shadow effect was enabled
before in 6.0, 5.0, 4.1 but not yet in 4.0.
