I don’t think this issue is fixed: it still occurs with some font and size combinations. To replicate, run ProJucer on macOS 10.12, use the Inconsolata font,and set the size to 12.0 in the ProJucer preferences. The code editor text disappears. In fact, if you scroll through various font sizes it seems that some work, and other don’t. Weird.
And the lag issue on macOS 10.12 mentioned above is still a problem. It seems that, when typing into the code editor - with any font, at any size - the most recent character is only repainted when the caret is repainted. This gives a weird laggy feeling where you’re not quite sure if the keypress was registered or not. Again, this can be easily reproduced in the ProJucer by editing any code file from within.
Any chance of a fix?
