Created attachment 144971 [details] Example slide PPTX I can't say whether this is a bug and worth reporting, but since fileopen is different from MSO and it was the same before, so regression suspected: 1. open attached PPTX that is slide 6 from Bug 50265 saved in MSO 2. see that some row heights in left NS table are different from MSO for rows "ns1.r01.ru., ns2.r01.ru.", "Не указаны", "Прочие" Repro with 6.2+ and since LO 5.0, it was the same as MSO before with 4.4.

Repro 6.5+.
I'd be inclined to use default importance. While in itself the difference is small, when it comes to interoperability, fidelity is important.

Not sure if this is worth further keeping open.
(In reply to Timur from comment #10) > Not sure if this is worth further keeping open. I think it's worth it. attachment 166356 [details] is also affected by the same problem

repro 25.8+ with comment 0's "50265 example slide 6 MSO 2013.pptx". I notice that this is fixed by my WIP patches for bug 165521 - marking as a dependency. Also fixed is duplicate bug 139494's "PPTX-table-wrong.pptx". While I can reproduce with comment 6, 11's "tabletest.pptx" on Ubuntu 20.04 (where the gray cell background doesn't extend all the way to the bottom of the cell), I can't reproduce with Ubuntu 24.04. I've heard there are font differences between those packages. So likely the underlying issue is different in this case. Duplicate bug 133935's "OnlineLearningStrategies_Share Single slide.pptx" seems to be something else already fixed.

You can see that the table should be larger - extending down onto the gray bar at the bottom of the screen.
Created attachment 200105 [details] 50265 example slide 6 MSO 2013.pptx_import-1.png: PDF overlay AFTER the patches for bug 165521 In this overlay, RED again is where MS Powerpoint places the content. You can see that the table and table-text almost perfectly overlap each other now.
Marking as fixed - the patches have been committed for LO 25.8.
Verified with last night's snapshot: Version: 25.8.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: a2c58edd20f243697a0790d323816094e319b2a7 CPU threads: 12; OS: Linux 6.13; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US That was an impressive hunt and fixing exercise, Justin!
