Description Maurits Lamers 2012-08-06 13:32:58 UTC

When editing a text which is in italics, some characters will have a part of it drawn at the cursors location, a d for example (using Monaco). 
When putting the cursor behind this d, the cursor will blink over the stem of the d, but when it 'unblinks' it just paints the background color, instead of the stem of the d.
The result is that the character almost reads as an a, instead of a d.

Reproducible: Always

Steps to Reproduce:
1. write a d in an italics font, in such a way that the cursor will overpaint part of the character.
2. put the cursor behind this character
3. Look carefully when the cursor disappears
Actual Results:  
A truncated character, the pixels the cursor took are repainted in the configured background color

Expected Results:  
A complete character, without truncation

Using Ubuntu 12.04, 
Kate Version 3.8.4
Using KDE Development Platform 4.8.4 (4.8.4)
Font used: Monaco

After looking a bit more closely, the problem doesn't always arise as I described above. 
A d in the middle of a word for example doesn't show the problem, but a d followed by a ) does show the problem

Cannot reproduce with other fonts (I don't have Monaco at hand atm). Are there other fonts with this issue? Does this depend on the font size?

I managed to make a screenshot of the problem. While Monaco is my standard font, it also turns out to happen when using MonoSpace.

Sorry, can't reproduce either :(
Perhaps some problem with 12.04 on your machine or just hard to reproduce, but in any case, without some way to do so, can't fix this :( Sorry :(
