SUMMARY antialiasing doesn't work. No matter if i choose it to be on or off in settings>draw anti-aliased it always draws without anti-aliasing. This makes it kind of unusable for my purposes as a simple graphical tablet supporting app for notes. http://i.imgur.com/DJGXaIy.png STEPS TO REPRODUCE 1. 2. 3.

Anti-Alias is only used for polygon, rectangle, etc. but not for freehand lines (Pen). I mentioned the reason in the comment in the sources: // never use AA - it does not look good for the usually very short lines
Hmm, that's not my expectation as a user. I think anti-aliased lines always look better than aliased ones. If you feel that there are use cases where anti-aliasing looks worse, could we try to have the code intelligently handle those cases, or making it configurable?
Anti-aliasing always looks better when I compare what is produced in kolourpaint and what is produced in xournal++ (with xournal++ looking much better). I think it is worth reconsidering or having an option to enable/disable for freehand lines.
Agreed. The pixelated lines just don't look good.
