Bug ID: 173156
Summary: roundtrip produces file with content not readable by
PowerPoint
Product: LibreOffice
Version: 26.2.0.0 alpha0+ master
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: regression
Severity: normal
Priority: medium
Component: Impress
Assignee: [email protected]
Reporter: [email protected]
Created attachment 208115
--> https://bugs.documentfoundation.org/attachment.cgi?id=208115&action=edit
Created by PowerPoint based on default template
Open the attached file "DefaultTemplate.pptx". It is based on the default
template of PowerPoint and contains two shapes on a "Blank" slide layout. The
file was produced in current PowerPoint 365.
Save the file as odp. Close the document. This is important to clear any cache.
Open the saved odp document and export it to pptx. Close the document.
Open the newly produced pptx file in PowerPoint. PowerPoint reports unreadable
content and wants to repair the document.
I see the problem in Version: 27.2.0.0.alpha0+ (X86_64)
Build ID: 46b82d13132e30e5abf68c571557cdc903c3d9d3
CPU threads: 32; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Raster;
VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: threaded
It was OK in Version: 26.2.0.3 (X86_64)
Build ID: 620(Build:3)
CPU threads: 32; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Vulkan;
VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: threaded
The problem is likely related to slideMaster, slideLayout handling. If I delete
all slide layouts in PowerPoint but the only one actually used, then the
roundtrip does not fail. I'll attach such file in the next step.
