   Hi Tailor.

   I wanted show two tests that I have done and two questions:

Thanks, Jose!  I've been hunting for more issues that might relate to
your problems.  Haven't found anything yet related to LVDS, but there
might be an improvement to rendering glitches now.

   1- If I disable the LVDS monitor in xorg.conf: Ignore option,  then
   xrandr shows only one display and the resolution is configured at
   1920x1080 the right resolution. What can I try to see if the detected
   LVDS display that doesn't exist in my PC, is a fault of NetBSD code or
   the Intel driver? Do you know some linux distribution with relase that
   is similar to the code used in NetBSD 7 for test it?

It is probably the fault of the NetBSD driver.  Our drm code is based
on Linux 3.15, so if you can try any Linux distribution with that, it
would be helpful.

   2- If I use AccelMethoed bitl, then artifacts in fonts in gtk2
   applications don't appear anymore. Only appear artifacts in graphics
   (icons) and photos.

   3- Does it work intel driver in NetBSD 7 for other people without
   artifacts at the moment?

You're not the only one seeing artefacts.  However!  Can you try with
sys/external/bsd/drm2/drm/drm_cache.c updated to rev. 1.4?

   4- Do I send my findings with gnats?

Yes, please!  Easier to make sure they don't get forgotten then.
