So I opened a c++ script made in Xubuntu and every tab character was highlighted with grey. That doesn't happen when I open scripts made on Windows. How do I stop Emacs from highlighting them, it's very distracting? Here is a picture of what it looks like: example

  • A guess is that you're using whitespace-mode, which is highlighting the Tab chars. Check the mode you're using for the buffers in GNU/Linux vs Microsoft Windows. Sounds like one of them turns on whitespace-mode and the other doesn't. Just a guess.

    Put the cursor on one of those Tab chars and hit C-u C-x =. The *Help* will tell you what faces are used to highlight them. Work from that info to find out what code (maybe whitespace-mode) is doing the highlighting.

  • Thank you! I'll check the settings and preferences as well.

You have whitespace-mode turned on. Turn it off.
