(originally reported against openSUSE: https://bugzilla.novell.com/show_bug.cgi?id=544924) All applications that are using clutter are not usable when using the radeon or radeonhd driver. A similar bug has been reported for intel 855GM cards (see bug 24140) Note this comment from upstream clutter developer: =========== usually, any bug in the event handling for Clutter is the direct result of a malfunctioning glReadPixels(). in order to identify the scene graph element that originated the event, Clutter encodes each actor's unique id into a RGB value and renders the scene graph using those colors. in this case, the warning: (test-events:8008): Clutter-CRITICAL **: clutter_id_pool_lookup: assertion `id < id_pool->array->len' failed means that the value extracted from the glReadPixels() output was not a valid id. =========== According to the openSUSE X team, it'd be an issue in Mesa. lspci tells me I have "ATI Technologies Inc M56GL [Mobility FireGL V5200]"
Is this bug still relevant? At least on my system Clutter apps (GNOME Games, GNOME Shell) seems to work without problems.
(In reply to comment #1) > Is this bug still relevant? At least on my system Clutter apps (GNOME Games, > GNOME Shell) seems to work without problems. Yes it is still relevant, unfortunately. On my Thinkpad T41 at least (ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]). All the Clutter based apps cause problems, especially in the GNOME Shell I get black windows only. Well, there seems to be some progress, compared with early versions of gnome-shell: In some cases I can see the window content, for example in Firefox. The Clutter based games (lightsoff etc.) don't show any usable content. For this reason, the affected games were removed from the most distributions. On the other hand, my video card with its 32 MB memory isn't completely unable to give a reasonable OpenGL experience. I'm able to use Compiz, with some speed restrictions anyway, but it works, although I prefer actually Fluxbox inside GNOME. May we expect any further progress for such graphics chipsets? In my case, I don't have the freedom to use the proprietary ATI driver, because for this chipset a driver was never written. And I don't expect to get such a driver in the nearest future or later, due to the age of my laptop.
(In reply to comment #2) > Yes it is still relevant, unfortunately. On my Thinkpad T41 at least (ATI > Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]). Isn't this r200 hardware? That's not covered by the r300 driver...

I've the same problem of comment #2 on a Thinkpad T41 too. The video card is r200/r100 hardware as you said: should we fill another bug?
I've noticed a particular condition: I can see the windows's content if I maximize them. Could be helpful? Again, I'm talking about an rv100 chip ( R100 ), should I fill a new bug or is it related to this one?
The classic r300 driver has been abandoned long ago. It was replaced by the Gallium driver r300g. If you have issues with r300g please file a new bug report with component Drivers/Gallium/r300 Thanks.
