--- Comment #6 from Mauro Rossi <issor.oruam at gmail.com> ---
Hi,

I performed a sequence of builds, reaching 10.5 branchpoint and the problem is
still there, I need to continue looking in i965 related commits back to 10.4
branchpoint, to cover all what happended in 10.5.0devel stage.

While performing tests I got evidence of glError by activating EGL logging,
in each and every case of font artifacts I get the following indication in
logcat:

10-18 23:21:25.597  3514  3605 D libEGL  : [glTexSubImage2D] 0x500

I checked that the 0x500 error was systematic by loggin 10-12 hazi font events
and the timestamps do match in all cases.

More info here:
https://groups.google.com/forum/m/#!topic/android-x86/zaz57OckjJs

I have enabled LIBGL_DEBUG, MESA_DEBUG, MESA_LOG_FILE environment variables,
but there I get no valuable log.

Does it help if I use INTEL_DEBUG environment variable?
All flags or a subset?
Will the output go in MESA_LOG_FILE?

Thanks for your indications
Mauro
