I am running pixinsight 01.08.03.1123 Ripley x64 on macbook pro retina, OSX 10.11.1.
The software run on the normal GPU, and don't use the hi-performance GPU.
The text on the windows looks a fuzzy, not as crisp as other software. even some very small text you see in some windows are unreadable.
The text on the menu bar, are crisp, and you can see a big diference between the fonts at the menu bar, and the text in the windows.
Thanks.
