GNOME Bugzilla – Bug 647588
Missing letters (W,A,T) with Gallium 0.4 / ATI Radeon / KMS
Last modified: 2015-02-27 02:17:48 UTC
Created attachment 185819 [details] Letters "A" and "T" are missing After some time of usage, GNOME3 with GNOME-Shell shows some artifacts. I've made a screenshot of one of them. GNOME-Shell doesn't display two letters: "A" and "T" in some places. After restarting shell, bug is no longer present. Since I didn't heard of this bug from other GNOME3 users, I assumed it's a driver-related bug. Hardware: Notebook Asus F5VL CPU Inter Core 2 Duo Graphic Card Ati Mobility Radeon X2300 Software: Arch Linux i686 GNOME 3.0 stable Linux Kernel 2.6.38.2 Xorg Server 1.10.0.902 libgl 7.10.2 ati-dri 7.10.2 xf86-video-ati 6.14.1 clutter 1.6.14 pango 1.28.4 GNOME Shell 3.0.0.2 mutter 3.0.0.0 Driver recognized in System Info is: Gallium 0.4 on ATI RV515. I have KMS enabled.
I'm seeing exactly the same missing letters sometimes, with a very similar setup: Hardware: Acer Travelmate 3200 Pentium M ATI Mobility Radeon 9600 Software: Arch Linux i686 GNOME 3.0.1 Linux Kernel 2.6.38.4 Xorg Server 1.10.1 libgl 7.10.2 ati-dri 7.10.2 xf86-video-ati 6.14.1 clutter 1.6.14 pango 1.28.4 GNOME Shell 3.0.1 mutter 3.0.1 Recognized driver: Gallium 0.4 on ATI RV350 KMS enabled
Attaching the output of glxinfo as an attachment is welcome. https://bugs.freedesktop.org/show_bug.cgi?id=35998 looks a bit similar, but for other hardware.
Created attachment 187444 [details] Output of glxinfo
weakhead: Does this still happen in GNOME 3.2?
Created attachment 210989 [details] glxinfo dump on debian wheezy with nv20 and nouveau driver.
It happens consistently for me on debian wheezy with nv20 and nouveau driver.
Could you report it to the Nouveau developers? Their bug tracker is at: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg Before that, it might be interesting to try a recent LiveCD of any distribution to check it still happens. Thanks!
Multiple things happens: 1 certain glyphs turns into a yellow block for example 'A' in activitites and '3' in the date. 2 The icon for the current window (next to 'Activities') turns into a yellow blob. 3 other characters for example 'l' in the low disk-space warning. 4 The transparent area at the bottom of the screen turns into a mostly solid yellow' This happens when a lot of ram is used so it is starvation related. I have 1G of RAM in this machine and the nvidia card has 64M.
I also get these (this is for google chromium): 1 'g' in tab titles is turned into a blue blob 2 'g' inside chrome's app menu isn't affected but 'B' is.
Is this still happening?
Yes, according to a new report filed today.

Has anybody filed a bug at freedesktop.org like Milan suggested in Comment #7 ?
Hello, I have same problem, some missing char in some menu, Just want to inform you that I enabled 'High Contrast' and 'Large Text' in Universal access settings and problem disappeared, but I can't tell you if solution is permanent. Have a nice day.

Jacques, weakhead, Ulrich, Stefan: Is this still happening to any of you with gnome-shell 3.14 or 3.12?
