Occasionally I have this ugly red underline in my python code. It seems not related to any flymake error/warnings. Does anyone know why it shows and how it can be removed? Thanks!
I am using latest elpy and emacs (24.4) on Mac OSX 10.9
The problem only occurs occasionally (but very annoying). Now it happens again. Here is the output of
describe-char on a SPACE character in red underline region:
