I just installed it on my WQHD ThinkPad running at 225% scaling and everything is blurry. It's definitely not running as a high-DPI-aware app. Are you saying there are some settings I can tweak to fix it? That would be great.
The TrackPoint response is all wrong too, but one step at a time... :-)
OK, I will wait a few more years. I love Smalltalk, but I don't think I am qualified to fix this myself, unfortunately.
