This is a minor, but optically nasty bug when working with other color-schemes.
How to reproduce (guessing the english names from german version):
- goto advanced editor settings
- enable "break line after max. number of character"
- enable "center document in editor"
- set number of lines to 80 (or smaller according to screensize)
- goto syntax highlighting
- change background to any color but white
- done
Now the left part of the edtior should be still white.
(sorry, the ticket was from me, I thought I was logged in)
This has already been fixed for the next release.
