Some fonts in DeltaWaker's text editors are not smooth on macOS. Why?

Occasionally, you may come across cases where some fonts in DeltaWaker's text editors (Cocoa-only) do not appear smooth on macOS i.e. they are not anti-aliased. DeltaWalker usually ensures that the fonts it uses are anti-aliased however those settings might get clobbered.

It's important to know that:

Monospaced fonts like Monaco are excluded from the anti-aliasing threshold.
Cocoa applications by default do not anti-alias the Monaco font.
Anti-aliasing of fixed-width fonts is controlled via the AppleSmoothFixedFontsSizeThreshold setting and not AppleAntiAliasingThreshold.

Executing the following command in Terminal (Application > Utilities) should take care of the issue:

defaults write com.deltopia.deltawalker AppleSmoothFixedFontsSizeThreshold 9
