rendering problems in libre office writer

Very often it happens for lines in Libre Office to be rendered strange. Selecting something on that line fixes it, but the bug moves to a lower line. See the screenshot. I have seen this bug for many versions on at least 2 different laptops, so it is an old one.

rendering problems in libre office writer

Another rendering problem: for some reason, sometimes, some lines appear to have a streak through white line (both on selected and not selected text). This one only disappears when scrolling text to get it out of the visible screen. See screenshot.

Thank you for reporting the bug. To be certain the reported issue is not
related to corruption in the user profile, could you please reset your
Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present

Please copy and paste here the contents of your Help - About. This allows us to know more about your system.

You could also test with a master (6.4) build as an appimage: https://libreoffice.soluzioniopen.com/

I think I've seen this problem on some systems, but I haven't noticed them on my own at least recently (and cannot repro now).

Change back to UNCONFIRMED after you have provided the information.

Hah, just as I claimed I had not seen it, I saw it. Two screenshots in one image file.

There may be an older report for this, but I could not find one.

I cannot really give steps to reproduce. I had focused away from the Writer window and when I focused back, the line had rendered badly. Selecting the line produced the effect seen on the left side of my attached image.

Dear florin.arjocu,

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
