Initial setup systematic artifact
There is a nasty font rendering problem affecting Intel GMA X3100/X4500
and other chipsets belonging to the same family driver i965GM.
The problem appeared with mesa 10.5, survived mesa 10.6, mesa 11.0 and it
affects also mesa 11.1.0devel.
Mesa 10.4 branch was completely unaffected.
There are many analogies between font artifacts observed on both kitkat-x86 and
lollipo-x86 builds which resemble the artifacts described in the following
links:

We tried very hard to isolate the commit causing this, which should be around
10.5 branchpoint ... 10.5.0 release, but a lot happened (format_pack, NIR and
i965)
Prime suspect is
Forcing MSAA antialiasing in Developer Settings does not solve the problem.
The GUI elements shown in the attachments are systematically affected with
10.6, 11.0 and 11.1.0devel, but in the latter the font artifacts started
appearing as vertical stripes, while in the former branches
Another clue is that all characters of the same letter appear with the exact
same artifact and Settings, Google Play are heavily affected by font
transparency, causing the GUI to be unusable.
S.O.S.
