Description Telesto 2020-12-14 21:25:33 UTC
Description:
Red underline squiggle line hiatus when when highlighting part of word

Steps to Reproduce:
1. Open the attached file
2. Zoom at 100%-120%
3. Select "tional"
4. Highlight it yellow.. notice the 'underline' changing waves 

It also causes shifting moving letters depending in zoom-level between 100-170% (but no clue if this VCL floating point topic).. so the wave distortion maybe related to.. or highlighting (and other formatting) is somehow affecting rendering'

So painting again/calculating starting at starting point of the change. Which is is in the middle of word in this case.. Should be less noticeable if this would happen at an empty space.. (space-bar area). This would at minimum mask the flawed better.. 

But needs someone with actual knowledge about this kind of thing :P

And yes, this topic kind of the area who cares. But still see it as a discrepancy with the superb situation

Actual Results:
The is break in the line at left where highlighting starts (but dependent on zoom level, zoom out and it's more noticeable) 

Expected Results:
Don't see any reason for the interruption the waves


Reproducible: Always


User Profile Reset: No

I can confirm it with

Version: 7.0.4.2 (x64)
Build ID: dcf040e67528d9187c66b2379df5ea4407429775
CPU threads: 4; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win
Locale: de-DE (de_DE); UI: en-GB
Calc: threaded

"Addetional" is underlind after opening and underlining of "tional" changes after highlighting.

I can't confirm it with master ("Addetional" isn't underlined after opening. But as far as I know master doesn't include spell checking by default. That might be the explanation.
Comment 3 Stéphane Guillou (stragu) 2023-06-07 13:23:11 UTC
Confirmed on Linux with:

Version: 7.6.0.0.alpha1+ (X86_64) / LibreOffice Community
Build ID: f97a7b965be154824e108802b386e3132b0a237a
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Also in OOo 3.3, so inherited.

Issue also happens with other formatting, like bolding part of the word. And in other components, like Calc.

Dear Telesto,

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
