Here is a copy of my config file. Place it into your "internal" folder within your QB64 folder. Rename your old config file first so you don't overwrite it. If this config works for you then it must be something in your settings causing this. If you get the same pixelated result then perhaps the version of QB64 you are using.

Note: I had to zip the file before I could attach it here. The forum software kept rejecting it in its original form.

It's the font itself that he's using.  That's how that character renders.
