I have not tested it extensively, but it seems it disappears if I use metacity instead of compiz. I also installed the whole kde4 desktop, and when I start a kde4 session, these problems seem to disapear (I use KWin in this case). I tried combinations of compiz options --indirect-rendering and --loose- bindings without any success. I also tried the nvidia hacks suggested on some web sites (InitialPixmapPlacement, ect.) since I have a 8400GS card, but it does not solve the problem.

It appears to only/mostly arise when Compiz is in use. The problem is caused by an Nvidia feature called "powermizer" that pushes the video card into low performance mode. Some people say some changes in xorg.conf help, but I tried them all and none mattered. On my Lenovo T61, I found that an option for the nvidia kernel module does help. You can force powermizer into a higher rate with a kernel module option. Here is the content of the option that fixes it for me. $ cat /etc/modprobe.d/nvidia options nvidia NVreg_RegistryDwords=3D"PerfLevelSrc=3D0x2222" options nvidia NVreg_Mobile=3D1 The Nvidia techs are aware of this and they have a beta driver that helps, but at the moment it randomly crashes the system.

If i go to the appearence settings and set visual effects to "None" the problem dissapears. I also tried with the updates from -proposed (nvidia 180 and i think there was a compiz update too) and the problem is at least as bad, if not worse. Single head setting on laptop, 1280x800 resolution screen. Nvidia card info from nvidia-settings: GeForce 8400M GS PCI Express 16x Any more info that would be useful just ask and i'll post it here. --===============8466202902961366055== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Author: Eric Butler (codebutler) Date: Wed, 14 Jan 2009 01:42:48 -0000 Message-Id: <20090114014248.26970.56466.malone@potassium.ubuntu.com> Hey everyone, I was also having this problem with Firefox and Qt4 apps.

The problem still occurs with latest 180.22 drivers from Nvidia though it seems that it appears only after a few seconds when scrolling (in open file dialog for example). --===============8466202902961366055== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Author: levien (levien) Date: Tue, 03 Feb 2009 14:38:42 -0000 Message-Id: <20090203143843.4543.8594.malone@gandwana.canonical.com> I experienced more or less the same redraw issues, on an up-to-date Intrepid AMD64 install with a GeForce 8200. The failures to redraw window contents occur only with desktop-effects turned on, and mostly in Firefox but sometimes also in other applications. I tried both the standard 177.82 and the new 180.22 nvidia drivers, but both experienced redraw problems. Additionally, the 180.22 driver destabilised USB and X.org on my system (interrupt issues?), so I had to switch back to 177. Next I tried updating compiz to 0.7.9-git20080918. This seems to have helped a bit, I now only get redraw issues after opening a lot of windows (>32). If I keep the number of open windows below 32, everything seems to be OK.

When this happens the Xorg process goes to 100% CPU use, and I need to log in remotely to either kill X or restart the system, because other methods (CTRL-ALT-DEL, CTRL- ALT-Backspace or switching to a text terminal) don't work anymore... Unfortunately the system logs don't give any indication of errors when this happens. I've switched back to 177.82 again, because at least this version is stable (for me). Also, the 180.27 driver still gave redraw issues. Here's slightly more detailed description: With compiz 0.7.8 all window updates would cease at the moment any application tries to go fullscreen (screensaver, image viewers, etc.). After I upgraded to compiz 0.7.9, at least this problem was gone and the redraw-issues were relatively minor and infrequent (or unpredictable if you will), and mostly occured in Firefox (haven't tried LastFM). However, when I open a lot of (I think more than 32) windows, the contents of the most recently opened windows isn't drawn or updated at all until I manually resize the window. My system has an Asus M3N 78 motherboard with a GeForce 8200 mGPU and a quad-core Phenom CPU. When I turn off desktop effects, everything works just fine. (To be able to switch easily I installed Compiz-Switch: http://forlong.blogage.de/article/pages/Compiz-Switch). I guess I'll just have to keep trying new versions of the nvidia driver as they are released... --===============8466202902961366055== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Author: Anakin Starkiller (sunrider) Date: Mon, 09 Feb 2009 19:54:58 -0000 Message-Id: <20090209195458.19707.73774.malone@gandwana.canonical.com> I think there are two separated problems (always with compiz activated) - one with QT4 apps - another with gnome-terminal for example --===============8466202902961366055== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Author: Anakin Starkiller (sunrider) Date: Thu, 12 Feb 2009 16:00:06 -0000 Message-Id: <20090212160006.20511.66381.malone@palladium.canonical.com> I may have found a dirty workaround.

I've been trying to track down the cause of this problem for ages, and your suggestion has just helped me find it. Apparently the redraw problems are caused by a race condition, which occurs with compiz in combination with nvidia driver versions above 177.76. According to nvidia developers at the nvnews forums: "[the cause of the problem] is a race condition between the X server and compiz that's the result of a fundamental design problem in the way the Damage extension works." and "[fixing it] will require more changes to the Damage and GLX extensions, the X server, Compiz, and the NVIDIA X driver." Because it is apparently caused by a design problem, it will probably take some time before the problem is fixed. The only real way to ensure it doesn't happen is not to use compiz. But on some systems it helps to change settings that affect the timing of pixmap uploads to the GPU. You can for instance try to disable the compiz "--loose-binding" option, or play with the powermizer settings. I just had a look at the wrapper script that launches compiz in Ubuntu. It enables --loose-binding on nvidia hardware (which in turn works around a performance issue with texture binding on nVidia cards), but it only seems to do this when indirect rendering is disabled (the default setting). So in theory this should disable --loose-binding without having to edit the wrapper script or (re)start compiz by hand every time: mkdir -p ~/.config/compiz; echo INDIRECT=3D0 >> ~/.config/compiz/compiz- manager It just adds "INDIRECT=3D0" to the configuration file ~/.config/compiz/compiz-manager, to force indirect rendering. This will of course degrade performance and disable some effect plugins, but if it works I would much prefer it to having the current redraw problems...
