Arch Linux

What hardware is this?

[«angvp@angvpbox ~»]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

Status with 2.13.0 from testing?

same here on thinkpad x41t (intel graphics). I have the feeling it is also depending on hinting/antialias settings. choosing a bigger font in FF while the problem occures, solves the problem sometimes.

Is this still an issue? Kernel, driver, libdrm, X and friends have been updated in the meanwhile.

for me it's still an issue, yes.

intel-dri 7.10.0.git20110215-1
xf86-video-intel 2.14.0-2
kernel 2.6.36

Intel Corporation Mobile 915GM/GMS/910ML Express Graphics Controller (rev 03)

sorry, refresh error

Does the problem persist with current stack?

Yes, the problem still occures. However i still don't know how to reproduce. When the problem appears in a browser, I can just increase the size of the font and that artifacts disappear and will appear just after a while. Then I can again try to increase or decrease the font size to cure the problem temporary.

I'm not even sure, whether it is a problem with only some specific fonts used in css or not.

<strike>IIRC that happens only in browsers (gecko _and_ webkit engines).</strike>

Edit: it happens also in terminals. Just switched to
urxvt*font: xft:Dejavu Sans Mono:size=8:antialias=true:hinting=true
in my .Xdefaults and got artifacts.

Can't remember experiencing this with that setting:
urxvt*font: xft:Envy Code R:size=9:hinting=true:antialias=true

I did some digging and it seems that is a variation of the following bug: https://bugs.freedesktop.org/show_bug.cgi?id=28151 . Feel free to chime in with the details provided here, maybe it will motivate the devs to have another look at it.

Please mark this bug as upstream.

I found a workaround here:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608

Using the DebugWait Option fixed the problem. But i think they have to fix it nevertheless.
I'm having this bug with Gentoo and i found this bug here :)

DebugWait option cured my fonts too.

I have experienced similar problems. Also problem in the title bar (they do not refresh correctly) with xg86-video-intel 2.15.0.2. I have installed xf86-video-intel-git-20110804-1 from the AUR instead (and its dependency) an there is a clear improvement but I can still see problem sometimes. I wonder what happens with the developement of this driver. I have see these problems appear and disappear and appear again according to the upgrade. Seems that upstream can nlot secure a stable version.

Status?

@Allan McRae (Allan) I had read on a forum (I diddn't remember where) that setting

Option "DebugWait" "on"

in the "Device" Section of /etc/X11/xorg.conf fix the problem of broken fonts. So this is what I did and I have no problem of broken fonts anymore but I have not tested it without the option (As the problem is rather random, we should test it for a long time to see the precise status). I have still problem with opengl: glxgears does not run smooth (it shoulkd syc the refresh rate with the screen: i.E. 60 Hz but that does not work well), the workaround is to puyt the fiollowing in /etc/drirc:

<driconf>
<device screen="0" driver="dri2">
<application name="Default">
<option name="vblank_mode" value="0" />
</application>
</device>
</driconf>

just fyi:

i installed intel 2.20 with sna on my gentoo machine and changed the accel method also to sna:

Option "AccelMethod" "sna"

and i removed the DebugWait line and i have a huge performance improvement and also got rid of the font bug. Maybe you will test this on archlinux, too.

Upstream bug report to track: https://bugs.freedesktop.org/show_bug.cgi?id=36326

I have similar problem with font corruption on my laptop (see the attached image). I have a nVidia graphics card. It might be related. It started after yesterday update.

pretty sure is the pixman, xorg updates

status?
