I’m have been using Atom for some days in place of Notepad++ which is not suited for my new 4K monitor.
It seems I have stumbled against what seems a bug of the program.
I program in C language, and in a file I have seen that pre-processor defines are not handled correctly.
I have taken a grab of the screen + inspector to show how Atom is interpreting those lines.
See that it is interpreting in a wrong way only few of them, not all.
I hope the image is clear as I can’t see how it has been filtered it in the preview.
If I add some char randomly (like leading whitespaces) it may color the line correctly. May. But not always and it may soon return to the default white color.
I hope this help narrowing the problem.
