Description muso 2017-03-15 14:49:44 UTC
Text fields in PPT and PPTX files have zero width in Impress.

This bug is a regression to Impress 5.2.x. It affects PPT and also PPTX files.
This bug makes Impress more ore less unusable and I had therefore downgrade to Impress 5.2.x for daily work.

Steps to Reproduce:
Open a PPT or PPTX file of your choice that has a text field. I also attached a very simple one-slide example PPT file.

Actual Results:  
The text fields have zero width. Therefore all letters of the field are placed upon each other, see the attached screenshot.

Expected Results:
Well, readable text of course.

Reproducible: Always

User Profile Reset: No

Dear Xisco,

many thanks for your help. I reset the userprofile but it did not help. I therefore used the radical way: I uninstalled LibreOffice _completely_. Afterwards I run CCleaner and also searched the registry manually. I had nothing left from LibreOffice.

Then I restarted the PC and reinstalled LibreOffice 5.3.1RC1 (64bit). But even then the problem persist. Restarting LibreOffice in safe mode also doesn't change anything. I am still lost. Can't you reproduce the bug when doing the same?: uninstall LibreOffice completely and then reinstall it using the 64bit installer of 5.3.1RC1?

thanks and regards

Today LO was released. i tried this version. I even also deleted Windows' font cache before reinstalling LibreOffice.

The problem persists: ALL (sic!) ODP and PPT documents I have ever created with LibreOffice have now the unreadable text boxes.

I note that when I click into a text box and decrease the font size, the text becomes smaller. But when i click onto the just changed text i see that the size have not changed in the settings: I changed text in size 28 to 14. But in the settings I still see 28 afterwards although that the text appears now smaller in LO.

Any help is highly appreciated!

This bug makes me crazy but I now found a workaround:

- open my test file
- save it as *.odp
- close the file and reopen the just created ODP

result: the problem persists

But now do this:

- open my test file
- save it as *.pptx
- close the file and reopen the just created PPTX

result: now everything looks fine.

It is so wierd that I will have now to open my ODP files I once created with LO 5.x and save them as PPTX to fix them.
Comment 8 muso 2017-03-16 18:51:29 UTC
I attached now the fixed PPT file that I created this way:

- opened my attached test file
- saved it as PPTX
- closed the file and then opened the created PPTX
- saved it as PPT

I hope that when you diff my test file and the fixed version you find the problem.

Reproduced with / Windows 7 with OpenGL rendering enabled, but not with default rendering. Also not reproduced with the old layout engine ("set SAL_NO_COMMON_LAYOUT=1" in command line before launching LO).

Muso, until the bug is fixed, a simpler workaround is to disable OpenGL by unchecking "Use OpenGL for all rendering" in Tools -> Options...; LibreOffice -> View.

The latest 5.4 master build I had was from the end of February, the bug was still in it, but might've been fixed since...
