It looks like this is a kernel issue rather than a xserver issue, as
kernel commit 3a69ddd6f872180b6f61fda87152b37202118fbc fixes the problem
for me:
commit 3a69ddd6f872180b6f61fda87152b37202118fbc

drm/i915: Set the Stencil Cache eviction policy to non-LRA mode.
Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
using separate stencil buffers. Without it, the GPU tries to use the
LRA eviction policy, which isn't supported. This was supposed to be off
by default, but seems to be on for many machines.
This cannot be done in gen6_init_clock_gating with most of the other
workaround bits; the render ring needs to exist. Otherwise, the
register write gets dropped on the floor (one printk will show it
changed, but a second printk immediately following shows the value
reverts to the old one).
