After evaluating this elisp, top reports 100% CPU utilization from X.
The face used here is a squiggly underline. I tried using another face,
isearch-fail face and that overlay was drawn just fine. I believe the
problem is isolated to this squiggly underline face. At first I thought
the issue was with flyspell, or flycheck, but these are just examples of
modes that such a squiggly underline.
I am running arch linux, without any desktop environment (I just use Xmonad and install
whatever else I might want). The computer is a Dell Precision M4700.
