Sometimes the emacs windows will flicker badly. This often happens when scrolling, just moving the cursor, or using clicking with the mouse on some part of the buffer. It can be reproduced with `emacs -Q` but it is much less pronounced than with my custom configuration. I can post it if necessary. The following steps can be useful to reproduce it: 1) Open a long C++ file. 2) Run (setq mouse-wheel-scroll-amount '(1)). 3) Mouse the mouse whell up and down fast. 4) Pay attention to the part of the screen that should show new content. Sometimes it will flicker a few time before stabilizing.
