Since upgrading to now-stable x11-base/xorg-server-1.9.2 and media-libs/mesa-7.9, I'm experiencing graphical glitches in several OpenGL games, such as gl-117, extreme-tuxracer and Osmos. This happens for both the Gallium and the classic Mesa driver. At least Osmos worked well right before the upgrade. I'm using a Radeon HD4300 video card with the open source drivers and KMS enabled. Reproducible: Always Steps to Reproduce: 1. Start an OpenGL game 2. 3. Actual Results: Graphical glitches (see attached screenshots) Expected Results: No glitches Portage 2.1.9.25 (default/linux/amd64/10.0, gcc-4.4.4, glibc-2.11.2-r3, 2.6.36-gentoo-r5 x86_64) ================================================================= System uname: Linux-2.6.36-gentoo-r5-x86_64-AMD_Phenom-tm-_9950_Quad-Core_Processor-with-gentoo-1.12.14 Timestamp of tree: Thu, 23 Dec 2010 14:00:01 +0000 app-shells/bash: 4.1_p7 dev-java/java-config: 2.1.11-r1 dev-lang/python: 2.6.5-r3, 3.1.2-r4 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 1.12.14-r1 sys-apps/sandbox: 2.4 sys-devel/autoconf: 2.13, 2.65-r1 sys-devel/automake: 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.4.4-r2 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.81-r2 virtual/os-headers: 2.6.30-r1 (sys-kernel/linux-headers) ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="*" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=amdfam10 -pipe -ggdb" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/config /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-O2 -march=amdfam10 -pipe -ggdb" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs collision-protect distlocks fixlafiles fixpackages news parallel-fetch protect-owned sandbox sfperms splitdebug strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="ftp://mirror.switch.ch/mirror/gentoo/ " LANG="de_CH.UTF8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="de en" MAKEOPTS="-j5" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/mnt/wfiles/portage-temp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/portage/myoverlays" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="3dnow 3dnowext X aac acl alsa amd64 bash-completion berkdb bzip2 cdda cddb cdr cli cracklib crypt cups cxx dbus dri dvd exif faac faad fam ffmpeg flac fontconfig fortran gd gdbm gif gimp git gpm hal iconv inotify ipod ipv6 java java6 jpeg kde kipi lame latex lcms lm_sensors lzma mercurial mmx mmxext modules mp3 mpeg mplayer mudflap multilib ncurses nls nptl nptlonly ogg opengl openmp pam pcre pdf perl png pppd python qt4 readline rss rtsp samba scanner sdl semantic-desktop session smp spell sse sse2 sse3 ssl svg sysfs tcpd threads thumbnail tiff truetype unicode vim-syntax vorbis vpx x264 xcomposite xetex xinerama xorg xvmc zeroconf zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de en" NETBEANS_MODULES="apisupport harness ide java nb webcommon websvccommon ruby" PHP_TARGETS="php5-2" QEMU_SOFTMMU_TARGETS="arm x86_64" QEMU_USER_TARGETS="arm" RUBY_TARGETS="jruby ruby18" USERLAND="GNU" VIDEO_CARDS="radeon" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

Please also attach dmesg output. Do you use compositing? Do you also see the glitches when starting OpenGL applications with LIBGL_ALWAYS_INDIRECT=1 ?
I do use compositing (KWin). I'm not at home right now, but I'll attach dmesg and try with LIBGL_ALWAYS_INDIRECT in a few days.
Created attachment 258237 [details] purple tint in desktop switcher widget Hmmm, I was just thinking of changing my package-specific bug to much the same summary. I've seen a few graphical glitches since doing the same upgrade, one of which I have documented as #348930, and another that I will attach now. I assume that any graphical glitch in KDE could be related, if one is using OpenGL compositing in KWin? What exactly is the glitch in ETR? Is it the purple banner thing? Of course I ask because the glitch in my KDE desktop switcher is the purple/indigo tint, which should not be there.
Oh, and by coincidence (or not), I also have an r700-era Radeon card (4850). I have only tested the classic driver so far because I thought gallium was still highly experimental for r600-r700.
Created attachment 258360 [details] My dmesg LIBGL_ALWAYS_INDIRECT=1 doesn't help. Neither does switching off compositing, though the symptoms change slightly. (The artifacts are coloured instead of black) To me it looks a lot like the textures somehow get corrupted.
@Jeremy: Yeah, the Gallium drivers are still experimental, but they're only an eselect away, so I thought I'd give it a try. :) There are actually several glitches in the extreme-tuxracer screenshot: those black squares on the floor shouldn't be there. Also this purple banner is shown multiple times. (It looks like the mipmaps somehow get mixed up or something) Additionally the tree in the foreground is torn.
Created attachment 258423 [details] KDE window shadow is a flat green rectangle. I hope you don't mind my piggybacking on your bug, Gian! But I assume we are suffering glitches for the same reason, so it makes sense to report in one place and pool data. Cheers.
@Jeremy: No, I don't mind. Have you tried extreme-tuxracer or gl-117, to see if you get the same glitches? I haven't seen any glitches in KDE lately.
ETR went weird as soon as the actual level started, I had to restart X. Maybe that was because I chose 2048x1152 and it wasn't expecting it. I'll try it again next time I want to reboot. gl117 had the same glitch as you, where the ground is covered in that repeating pattern of something... planes? We should try downgrading mesa and xorg-server separately, see if we can isolate the problem to one or the other.
I tried: neither downgrading xorg-server alone nor xorg-server and mesa helped.
(In reply to comment #12) > I tried: neither downgrading xorg-server alone nor xorg-server and mesa helped. Hold on... surely downgrading both of them must have fixed it? Otherwise this bug is misleading, as you said "Since upgrading..." in your description. I just downgraded mesa back to 7.8.2 and I haven't seen any of the glitches that I was experiencing yet, however gl-117 still had the same glitches and ETR just crashed so I have removed it. So I think you and I are talking about different glitches after all, even though your summary seemed appropriate for mine. I think the glitches that I'm seeing are specific to mesa-7.9 after all and not related to xorg-server. If you cannot resolve the glitches by downgrading X and mesa, then you need to consider changing the summary so that it's not specific to those versions. However, keep in mind that downgrading X completely is a tedious process given all the packages in x11-apps, x11-libs and x11-proto that may affect the result. Anyway, I leave you to it, good luck! :) Sorry about the noise after all.
Turns out that the problem wasn't the X server nor mesa, but the new kernel. I had also upgraded the kernel to 2.6.36-r5 right before upgrading X, and going back to 2.6.34 solved the glitches.

Is this still a problem with a recent stable kernel, or has this issue faded away?

Definitely faded away for me.
If anyone can still reproduce this on recent versions, feel free to let us know.
