See Bug 111848
TABS are lost in transition (see slide 7 in examples)
example attached to above bug
Comment 1 Jacques Guilleron 2017-08-16 16:44:41 UTC
Reproduced with
LO 5.4.0.3 (x64) Build ID: 92c2794a7c181ba4c1c5053618179937228ed1fb
Threads CPU : 2; OS : Windows 6.1; UI Render : par défaut; 
Locale : fr-FR (fr_FR); Calc: CL
only in PPTX format however.
Comment 2 Elmar 2017-08-17 05:45:48 UTC
Correct, the PPT version saves fine. 
I added it for comparison.
The dilemma is that in the PPT version (even though many probably do not use it anymore) one has the problem of losing the autofit setting (see  bug 111859)
Comment 3 Elmar 2018-05-30 05:29:18 UTC
The tab issue works fine in the Impress doc saved to PPT.

However, the PPTX save does not view correctly in Powerpoint and also Impress.

Can you retest please?

Comment 10 Elmar 2020-05-14 05:01:04 UTC
I am not sure what I am looking at, but when I display the two files in v7, they are still the same.
This was reported so long ago.
In the PPT version slides 7 and 8 display correctly.
In the PPTX version they do not.

I did also save the original ODP again into both versions using LO v7, and get exactly the same results

I have also displayed both files in Office 365 and get the same results.

I then opened the original ODP version in Office365 and saved it as a PPTX.
You can see the results for yourself - slides 7, 8 do not even appear, and you can see how the formats of all the other slides have been changed.

Bottom line: it this time with any version of LO, it is safe to say one should only consider saving to PPT.

Comment 14 Elmar 2020-05-15 05:04:47 UTC
Very interesting.
I saved the PPTX early yesterday morning after testing it in Windows MSO365.
I then did an update in Windows (took almost all day - >1GB download)
This morning I tried using both the online version of MS365 (the new name) and the full version in the VM.
Hey presto, it looks like your screenshot!
Other things resolved are that the fit-to-frame was working.
Only quibble is on slide 8 where the rounded rectangle is slightly off.

So, I guess this is just typical MS.
Since introducing their "good enough" policy more than 20y ago, they are driven by delivery date concerns and things like following their own standards (which they change anyway when it suits them) are much lower on the list of priorities.

I see that online MSO365 will not open ODP files.
In the full version (I run Win10, Win7, XP in VM with equivalent versions of MSO because MS will often not read older versions of their own files, notably, MSProject, OneNote) I can open ODP, but it is still an embarrassing mess and would not be able to use it when facing the public.

Kudos to you and team for doing a much better job than MS which really does not seem to care in spite of all the billions they make in profits. Very sad. Maybe if Bill had to spend some of his marketing-friendly charity billions by improving the quality of his product... A leopard does not change his spots. So I don't hold my breath.

As far as I am concerned, you can close this as resolved.

I noticed this as well. You can report it as a separate issue and add me to Cc.
