Presentation with gradient background

Make sure Skia is enabled.
Open attached file. The background is a fill with gradient from blue to gray.
Start presentation.
Error: Background is solid fill with default color.

Make sure Skia is disabled.
Open attached file and start presentation. The background is a gradient, same as in edit mode.

I see the error in Version: 7.4.0.0.alpha0+ (x64) / LibreOffice Community

Comment 1 Roman Kuznetsov 2022-03-03 18:27:35 UTC 
confirm the problem in

Version: 7.4.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: dc99d27f04b47c173de934a19b6d6a3cc572c20a
CPU threads: 4; OS: Windows 6.1 Service Pack 1 Build 7601; UI render: default; VCL: win

and I see the problem in 7.1 and 7.2 too but it looks some different than in 7.4

I see two issues:

From 7.1.0.3 to 7.3.0.0, the gradient looks only inverted (clearer at the top, darker at the bottom).

Version: 7.1.0.3 (x64) / LibreOffice Community
Build ID: f6099ecf3d29644b5008cc8f48f42f4a40986e4c
CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: en-GB (en_GB); UI: en-GB
Calc: threaded

In 7.4.3.2, the gradient looks nearly lost, but it actually spans the whole slide, the change in colour being very faint. The order is still inverted.

Version: 7.4.3.2 (x64) / LibreOffice Community
Build ID: 1048a8393ae2eeec98dff31b5c133c5f1d08b890
CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: en-GB (en_GB); UI: en-GB
Calc: threaded

Also in a recent master build:

Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 9b46020c262045aed0beace4708565235c2523cc
CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: en-GB (en_GB); UI: en-GB
Calc: threaded

That second part is I think a the same regression as described in bug 151703.
Comment 3 Stéphane Guillou (stragu) 2022-12-22 00:14:36 UTC 
...and the first part is not reproducible in:

Version: 7.0.0.3 (x64)
Build ID: 8061b3e9204bef6b321a21033174034a5e2ea88e
CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: en-GB (en_GB); UI: en-GB
Calc: threaded

So it's the regression described in bug 145845.

We can close this as a duplicate, I'll go with the more recent regression.
