<pre>Description:
When you want to see, what I see on my PC, open the attached file:
"Writer bad spaces, Tahoma, without Anti-Aliasin Font10.5.png"
When opening the picture: Make sure that you view the images 1:1 (100%) and
that anti-aliasing is switched off in the image viewer. (For example
Menu->Edit->Settings in "Nomacs").
What can you see in the picture?
An example: In the word "Kunde" with the arrow, "u" and "n" stick together. But
in the word "wundersamen", "u" and "n" do not stick together. There are a lot
further examples in this text, without arrows.
So this is what bothers me: The spaces between the letter look not always the
same.
(Please note: I do not want to use such modern technique like Anti-Aliasing. I
think Anti-Aliasing is good for 4K monitors. But I have a 1280x1024 pixel LCD
monitor. I know that most people use Anti-Aliasing on a 1280x1024 LCD monitor.
But I do not like it. I would rather have a crystal-clear writing with stairs
than a light blurred font without steps. )
Letters stick together at Tahoma without anti-aliasing
-----------------------------------------------------------------------------------
-Where can we observe this?
Answer: In the LibreOffice Writer. At any font size. The most error-free font
size is 10 (108dpi).
Please have a look at the attached File "Beispiel für jede Textgrösse.odt"
-Can you see the phenomenon also in Featherpad and Geany?
Answers: At font size 9 (108dpi) it occurs in Wirter, but not in Featherpad.
At font size 9 (108dpi) it occurs in Writer, but not in Geany.
-What happens if you enable anti-aliasing (with 10.5)?
Answer: Then the spacing is better. But there are still a few bad spacing
issues. Please compare the attached file "Writer bad spaces, Tahoma, with
Anti-Aliasin, Font10.5.png"
-What are the letters that always stick together?
Answer: That is different. Sometimes they stick together, a few words later
they don't anymore.
-Does the phenomenon also occur with other fonts? Microsoft fonts, or even
Linux fonts, like DejaVu sans?
Answer: DejaVu Sans: Yes, but much less. Arial: Much less, but irregular
spacing. Attached is an example for DejaVu: File "Font DejaVu Sans.png"
Steps to Reproduce:
1. Install Tahoma on your Linux system
2. Disable Anti-Aliasing on your System
3. Disable in Writer "Smooth screen fonts"
4. Disable in Writer "use Anti-Aliasing"
5. Open the attached document "Beispiel für jede Textgrösse.odt"
Actual Results:
The spaces between letters are irregular. Some letters stick together. Other
have normal spaces. Other have too much space between them.
Expected Results:
The visual impression should be that all distances between the individual
letters are the same.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
I have tried to enable OpenGL. But when I enable it, close Writer. Open it
again, then OpenGL is disabled again. *Confused.
Output from terminal:
