            Bug ID: 138918
           Summary: Red underline squiggle line hiatus when when
                    highlighting part of word
           Product: LibreOffice
           Version: 3.5.7.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

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
