I installed Atom 1.15.0. X64 on a Redhat 7 VM today. After I started atom, and open an .py file, I could not see anything, only the blank screen. I tried to create a new file, I could type in characters because when I switch to use vi I could see the the characters I typed in.
However, I could not see them on atom editor besides the red underline dots, which means wrong grammer/words, I guess. I feel the font color was set to white or the same color as the background by default, but changing UI or syntax theme did not help.
