Description mdcclxv 2023-05-04 17:38:31 UTC
Description:
When anti-aliasing is disabled, using the same Verdana font and size, Writer renders everything ugly as opposed to Calc which renders it clean and crisp.

Steps to Reproduce:
1. Install Verdana font
2. Create a Calc document using Verdana 11
3. Create a Writer document using Verdana 11

Actual Results:
Font rendering in Writer is totally ugly as opposed to Calc which does perfectly.

Expected Results:
Clean and crisp font rendering in Writer as well.


Reproducible: Always

I went to Tools - Options - View and unchecked both "Use anti-aliasing" and "Screen font antialiasing", but I can't get the text to look like in your screenshots. Can you help me find the correct option?

I realised that I need to go to System settings - Appearance - Fonts in KDE and deactivate anti-aliasing there. After that, I could see Writer renders Verdana worse than Calc.
