Log

Recent versions of xf86-video-intel driver in Arch Linux started showing
graphical corruption/artifacts (running XFCE plus compton compositor).  The
artifacts are sometimes bits of other screen contents, sometimes random memory
patterns.  They are showing up most frequently in tooltips (especially from the
date/time applet) and when using rubber-band selection in Thunar.

Last good version:
1:2.99.917+587+gc186d4d-1

Tested bad versions:
1:2.99.917+604+gff0ab2c-1
1:2.99.917+622+gde44aaa-1
1:2.99.917+626+ga7526ea-1

Related software versions:
xorg-server 1.18.3-1
mesa 11.2.0-1

Hardware:
Dell Latitude E5530
Intel Core i5-3210M (Ivy Bridge)

Xorg.0.log is attached, and screenshots will be uploaded shortly.
