Description of problem:
Some characters are missing on screen (see attached screen dumps)

Version-Release number of selected component (if applicable):
Fedora: 4.0.5-300.fc22.x86_64
        xorg-x11-drv-nouveau-1.0.11-2.fc22.x86_64

How reproducible:
Always

Actual results:
Text in menus, window title bars, in documents etc. have some characters missing (whitespace shown instead)

Same symptoms as bug #1194298, except that I had no problems on F20 and F21.
Rebooting does not make a difference.

Comment 2 Bill C. Riemers 2015-06-29 13:09:32 UTC 
I don't see missing characters anymore in Fedora 22, but I still occassionally see substituted characters.   For example I was viewing a wikipedia article the other day where all the "if" and "iff" character sequences where replaced with some type of heart symbol.   Copy and paste into gedit revealed the correct characters.     I'm thinking his might be a memory overwrite issue in a library such as libiconv rather than a rendering issue.
Comment 3 Kåre Løvgren 2015-07-01 18:50:40 UTC 
A new situation:
The missing letters situation got so bad, that the PC was practically unusable.
A hunch I had got me to remove the xorg.conf file I had to create as a workaround for bug #1215444, and it seems like it solved the missing letters problem (and the issue from the old bug seems to have disappeared; everything looks OK without this file).

Unfortunately, the system still hangs after a while as described in bug #1224808.

I get this on my fresh install of Fedora 22 on an ASUS P9X79 WS with a Xeon E5-2650L and a NVIDIA GeForce GTX 750 Ti running straight default gnome on top of nouveau. Real annoying! What's going on?

gnome-shell-3.16.3-1.fc22.x86_64
kernel-4.1.6-200.fc22.x86_64
xorg-x11-drv-nouveau-1.0.11-2.fc22.x86_64

Just let me know what other information might be useful to solve this issue.
