Sample slide (PPTX)

1. Open the sample PPTX file
2. Observe that part of the (small) dotted line is not visible in edit mode.
3. Enter presentation mode
4. Observe that a similiar (but smaller) part of the line is not visible

Version: 7.5.0.0.alpha0+ / LibreOffice Community
Build ID: 4e2ce2a460458f17ee4360c45a2da2fc4b4d753e
CPU threads: 8; OS: Linux 5.18; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US

All the way back to LibreOffice 6.4. At one point around 7.0 presentation
mode turned much worse, losing larger parts of the line, a regression which
was addressed via bug #136957.

Screenshot in Edit Mode

I see something a bit different. See attached image.

Some segments are thinner than others, but they're visible.

Dear Gerald Pfeifer,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
