<pre>I was asked to report this here after I inserted comment number 27 in
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1323762">https://bugzilla.redhat.com/show_bug.cgi?id=1323762</a>
The problem concerns corruption of text displayed on gnome utilities on my Dell
Latitude E6410 using intel graphics, running Fedora 22 and and Fedora 24 with
ctwm window manager.
I seem to have fixed the problem on that machine (using f24) by inserting
Option "AccelMethod" "uxa" in /etc/X11/xorg.conf.d/20-intel.conf, i.e. I
created a file /etc/X11/xorg.conf.d/20-intel.conf
containing:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
based on instructions found here:
<a href="https://fedoramagazine.org/solution-graphics-issues-intel-graphics-chipsets-fedora-22/">https://fedoramagazine.org/solution-graphics-issues-intel-graphics-chipsets-fedora-22/</a>
Scanning bug reports I find different sorts of font/text corruption problems
reported. E.g. a different problem is reported on this site in
<a class="bz_bug_link
bz_status_NEW "
title="NEW - xf86-video-intel, skl: Text corruption in variety of cases -- Firefox, Konsole, and more"
href="show_bug.cgi?id=95368">https://bugs.freedesktop.org/show_bug.cgi?id=95368</a>
So similar wording in the bug reports may be misleading.
The problem I reported did not affect the vast majority of text displays,
including use of xterm, firefox and other browsers, liberoffice, other editors.
It affects *only* gnome related text corruption, e.g. in gnome-control-center
and other displays concerned with sound/volume control, sound recorder, and
networking. It also affected xclock.
I don't have any screenshots, and I have now fixed the problem on my laptop by
using the "uxa" option. However examples partly similar to the ones I
experenced are shown in attachments in various bug reports. The symptoms
include mainly missing characters, but in some cases characters are displayed
in a corrupted form, e.g. with black blotches.
Using google, I found similar bug reports, with similar sample images, on
several different web sites not part of the fedora or redhat bug reporting
mechanism, so it is not a problem specific to fedora. A few users reported
successful use of "uxa" instead of "sna" but in most cases users and their
advisors seem to be completely in the dark. So it looks as if a fix is needed
across distributions, without users having to edit configuration files, though
that has worked for me.</pre>
