Description Volga 2017-12-10 15:36:50 UTC
Description:
If a combining placed very higher, the top edge could be overlapped. Reproduce with Doulos SIL Cipher: http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=CipherMusic

Steps to Reproduce:
1. Download DoulosSILCipher-1.020.zip

Not reproduced. It might be that a new HarfBuzz fixed the problem.

Set to NEEDINFO.
Change back to UNCONFIRMED, if the problem persists with 6.4. Change to RESOLVED WORKSFORME, if the problem went away.

screenshot of issue in LO 7.3 alpha0

The issue is inconsistent, which would explain why it was not reproduced in Comment 7.

In a recent master build, I opened the document after installing the font, and reproduced the issue, as see in this screenshot.

However, after zooming in or out, or resizing the window, the font displayed properly. (screenshot in next comment)
You even might get a very quick glimpse of the characters properly displayed when opening the document in the first place.

Maybe a hint at what the issue is: if you select the line of text, you'll see that the part that is not painted is whatever is outside the selection rectangle.

So is the issue related to how LO paints the viewport, somehow?

Comment 16 QA Administrators 2023-08-01 03:16:24 UTC
Dear Volga,

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
