Description

2 years ago
I sometimes see:
  - a context menu, immediately after opening it; or
  - the entire content area in the Firefox window, after activating it
being rendered black for a fraction of a second before the proper content is rendered.

I started seeing this in the 33.1 release (originally reported in https://bugzilla.mozilla.org/show_bug.cgi?id=1097417#c4), and have been seeing it ever since, though not very often. I think Bas said at one point it may be related to OMTC.
