[Lazarus] Lazarus IDE text display

[Colin Western]

Working on High Sierra Lazarus compiled for Cocoa shows odd character spacing for program text - each character looks about twice the width it should be. If I compile Lazarus for carbon it looks fine, and text spacing in my apps looks OK, so I suspect a SynEdit related issue. I though I had seen some earlier comments with a similar issues but I can't now find these. Any suggestons?
