Gargoyle doesn’t look so good on HiDPI OSX Retina Display. code.google.com/p/garglk/issues/detail?id=192
I will accept hardware donations so I can improve the support. 
A couple things to try:
- Set lcd to 0 in garglk.ini
- Set gamma to one of the other suggested values, like 0.7 or 1.4
I was concerned with this possibility when I read about the way OS X does the scaling for Retina displays. It’s possible that a more elaborate approach is needed; I believe Chrome had similar problems for similar reasons - it uses skia for to render text instead of relying on the platform.
Adjusting those settings doesn’t seem to help.
Apple provides documentation for testing HiDPI on conventional screens, so hopefully a hardware donation won’t be required in this case.

Gargoyle uses SDL, right? It looks like HiDPI support for SDL is an area of active research. forums.libsdl.org/viewtopic.php?t=8326
SDL is only used for sound; Gargoyle draws its own text and graphics.
This looks like it’s going to be a fun one to support. Thanks for the link to Quartz Debug; that can be my fallback plan if the kindness of strangers proves unreliable.
Hey, has anyone found a way to treat this? Gargoyle is not really useable on Retina MBPs, so I switched back to Zoom for now.
