        <pre>top looks perfectly normal, Gnome Shell is at about 8%, below are the first few
lines of perf top:

 25.91%  nvidia_drv.so                            [.] 0x00000000000935a0
  5.51%  [drm]                                    [k] drm_clflush_page

  1.92%  libv8.so                                 [.] 0x0000000000242052
  1.53%  libglib-2.0.so.0.3800.1                  [.] 0x000000000008986e

(Note: I'm running a low-latency kernel. No idea if it matters.)

The lag persists after turning on FORCE_16BIT_XFER.

Where do I set Option "AllowSHMPixmaps" "true" ?

Compilation with DBG=1 gives me plenty of errors in 3310ee89c1f1a.</pre>
