[Bug 88584] [ilk] Font and screen corruption in GTK+ applications

--- Comment #29 from Aaron Sloman <a.sloman at cs.bham.ac.uk> ---
There seem to be lots of bug reports on lots of different web sites complaining
about text corruption in gnome utilities (apparently not in other applications,
e.g. firefox, libreoffice, opera, terminal windows, etc.) -- including
freedesktop bug reports, bugzilla.redhat.com and elsewhere.

I wonder whether there is a central place where this this should be reported so
as to get it fixed?

I am using a workaround that was recommended here:
https://fedoramagazine.org/solution-graphics-issues-intel-graphics-chipsets-fedora-22/
and also in various bug reports, namely 

I.e. create a new text file /etc/X11/xorg.conf.d/20-intel.conf containing

Section "Device"
Identifier  "card0"
Driver  "intel"
Option  "AccelMethod"  "uxa"
EndSection

I am using a test kernel that was recommended to fix another i915 bug
(hanging):

4.8.0-0.rc8.git2.2.fc26.x86_64 #1 SMP Thu Sep 29 21:09:26 UTC 2016

though it did not fix the text rendering bug.

My hardware (vintage 2010, and generally still excellent):

00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor
Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA
controller])
        Subsystem: Dell Latitude E6410 [1028:040a]
        Flags: bus master, fast devsel, latency 0, IRQ 31
        Memory at f0000000 (64-bit, non-prefetchable) [size=4M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 70b0 [size=8]
        [virtual] Expansion ROM at 000c0000 [disabled] [size=128K]
        Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
        Capabilities: [d0] Power Management version 2
        Capabilities: [a4] PCI Advanced Features
        Kernel driver in use: i915
        Kernel modules: i915

I have only had this problem in the last year or so, using fedora 22. I hoped
that a switch to f24 would fix it, but not so.

Did someone change graphic drivers to use acceleration facilities on new
hardware without checking whether the software is running on old hardware?

It's strange that the bug affects only text in gnome displays (e.g. network
panel, volume control, sound recorder, etc.).
