<pre>After the latest xf86-video-intel update in Arch Linux from version
2.99.917+654+ga508b11 to 2.99.917+662+gb617f80, several people, including me,
have started experiencing "lag" in certain applications. What happens is not
exactly lag, it's that the screen (or maybe just the particular application?)
stops updating until triggered by something like mouse movement. I did a
bisect, it's commit 46ffdf2 "sna/dri2: Avoid chaining swaps across a mode
change" that causes it.</pre>
