mcc also has the same problem-- the sidebar menu items are also fractured.
Comment 3 w unruh 2015-09-29 07:49:37 CEST
Hmm. Sorry it seems to have been a problem with my kde. removing .kde4 and re-loggin in and the fonts are now OK. I think this can be closed. 
No idea what happened, but it is nice to have it work again.
Comment 4 Thierry Vignaud 2015-09-29 09:23:25 CEST
What's the outpuf of the following command?
lspcidrake -v |grep Card:

Please also attach (not paste) your /etc/X11/xorg.conf file.

xorg.conf

Card:Intel 810 and later: Intel Corporation|82915G/GV/910GL Integrated Graphics Controller [DISPLAY_VGA] (vendor:8086 device:2582 subv:8086 subd:4147) (rev: 04)

Attached is xorg.conf

Note, I went back to the old .kde4 where I was experiencing the problems, and the problems have disappeared. (I just moved away the new .kde4 and moved back the old one, did atl-ctrl-BKSP twice and relogged in). The fractured fonts are not there and my mcc refuses to start up for me unless I log in as root, just as it did on the new .kde4. Thus the reestablishment of .kde4 also seemed to have some other byproducts-- some changes elsewhere in the OS than just to .kde4

return of the corrupted fonts

And the corrupted fonts have returned. No idea what triggered it. This is new picture of the mcc front page. Note the fonts on the menu bar on the left.
Comment 7 w unruh 2015-10-01 19:23:03 CEST
In the attachment the corruption on any line may or may not disappear if that line is selected, or something else it done. I have Focus follows Mouse, and if I move the mouse into another window, then the highlighted left menu item suddenly uncorrupts. It stays uncorrupted even if I return to that window  until the mouse moves over that menu item again, or a neighboring one, or????  at which point it corrupts again.

The fractured fonts are still back, despite having done the latest update to the system. 
Also if I run mcc from another computer with X11 forwarding the fractured fonts are there.

Libreoffice menu fractured fonts

The problem is also in Libreoffice menus. This attachment is of the Libreoffice menu showing the fractured font there.
Comment 10 w unruh 2015-10-24 07:05:51 CEST
And Gimp, and Sound Recorder, and Xsane have fractured fonts. But not k3b, not SystemSettings, not VLC, not KeePassX.

Comment 11 w unruh 2015-10-24 07:27:51 CEST
And now I logged out of the X window, and then logged back in, and the fonts in the various programs are not fractured. Ie, something seems to be progressively corrupting the fonts. 
Any hint as to how I can figure this out.
Comment 12 w unruh 2015-11-04 19:15:02 CET
Tentatively this seems to be solved by the suggestion in 
bugs.mageia.org/show_bug.cgi?id=16655#c75

Ie, add a line
Option      "AccelMethod"  "uxa"
to /etc/X11/xorg.conf in the 
Section "Device" 

I have only tried this for the past 1/2 hour on a freshly rebooted 4.1.8 kernel (the problem I had was in 3.19.4 and got worse with time but also occured in 4.1.8) and the fonts seem to be OK. Will keep trying this and report if the font corruption reoccurs.
Comment 13 w unruh 2015-11-07 15:19:02 CET
After 2 days, still no font corruption and not desktop corruption. This seems to have fixed the problem.
Comment 14 w unruh 2016-02-06 19:29:23 CET
I am still getting corruptions of the graphics. Now it is not immediate, but sometimes if I leave a window open for a while, suddenly stuff will be corrupted. 
As an example I will include and attachment which is an image of an xmaple window which was left up for a while. ( about 4 days) When I looked at it this morning this is the mess I found. A large number of the lines in the graph had been displaced by about 20 pixels to the right. Ie, something in the Intel graphics driver is badly behaved. 

I am still using the Option      "AccelMethod"  "uxa" in /etc/X11/xorg.conf file.

The font corruption is also still present in the sense that if I leave a window open for a while, it becomes corrupted. In the past it was immediate (Ie I would open the window and the font would be corrupted). Now if I leave it open for a few days, I might find that the font is corrupted after a few days. 

One thing that might be correlated with this, is that another user uses the same computer with 
startx -- .1
and it seems as though their use of that other instance of X running is correlated with the corruption on my window. However, because everything is so sporadic, I have not been able to verify a causal relation.

png screen grab of xmaple fractured graph after a few days.

This is the screen grab of the effect mentioned in the last post.

Comment 17 w unruh 2017-02-03 12:17:38 CET
No idea, but since I last updated to the latest cauldron (four days ago) I occasionally get
the konsole screen having almost all of the lines with the same kind of corruption.
Ie, it seems every second line of pixels or something like that is displaced to the right. This is not persistent So if I open another konsole, the original one fixes itself and the text is fine again.

Not at all sure what triggers this font corruption.I have not been able to capture it yet in a picture. 
I also do not know if konsole is a gtk program.

Note that this is far less frequent an occurrence than when I fist complained a year and a half ago. Certainly for the 3/4 year I have not seen this effect in Mga5 or Cauldron.

This is in cauldron. I do not run Mga5 on the machine I am using these days (Dell xps13 laptop).
Comment 18 w unruh 2017-02-03 12:26:10 CET
Just happened again. I opened okular from commandline in Konsole, and paged up through the many error messages okular produces. And suddenly the fractured screen came up. I tried to take a screenshot, but that act fixed the font on that konsole, so, except for some lines missing their bottom or top of all the characters, things looked fine. 

(Notice that this effect of as if a fold in the screen is quite common. Is it related to the fractured screen? No idea. -- I will include that screenshot just in case it is helpful.

I fail to see any missing pixels in that konsole screen /o\

When you look at the picture using a different system, do you then still see missing pixels?

Do you?
Comment 22 w unruh 2017-03-12 12:09:17 CET
Nope. I also cannot see them on my current system. Strange. 
They were definitely there (or rather not there) when I posted. 
I have upgraded cauldron since then, so that may have been it.
