Bug 72093

Is this still an issue with a newer glamor version?

yes, And in Mesa 10.1-rc

I think this is a duplicate of bug 71190

Could you test with current git master branch.
This patch [1] should help. 

[1] http://cgit.freedesktop.org/xorg/driver/glamor/commit/?id=073c97f494ffe67b15b7a6a95fa894c3e109d862

nope still there. I assume the display manager (currently using KDM) is suppose to restart the X server after a crash right?

Are you sure that you get this with the commit mentioned above?
Because the error message "destination is framebuffer incomplete" has been removed with that patch.

<snip>
- FatalError("destination is framebuffer incomplete: %s [%x]\n",
- str, status);
+ glamor_fallback("glamor: Failed to create fbo, %s\n", str);
+ err = -1;

There is no glamor symbol in this log. Could you possible to get a gdb back trace or build glamor with debug symbol then get a new log? Thanks.

The root cause may be:
[  1230.077] XXX fail to create fbo.

Which means a glamor_egl_create_textured_pixmap() failed to set a texture
to a pixmap. This is an unexpected situation. As the texture is created
from an image which already allocated on the gpu memory, this call should not fail. Maybe we need to change the logmessage to an assertion. This bug should
be related to the ATI driver. The key hint here is to investigate how the function glamor_set_pixmap_texture() which is called in glamor_egl_create_texture_pixmap() fail to ensure the texture to a fbo.

I have zero experience programming drivers, much less debugging. I probably wouldn't know what to look for.

Alex,

I believe this should be a driver related bug. You may want to take a look.

Backtrace from xorg after a try to open OpenGL tab in Kinfocenter

I have the same bug. Maybe this backtrace will help.

Another backtrace after building mesa with debug symbols.

When building galmor, xorg-server, xf86-video-ati, glibc and mesa with CFLAGS="-O0 -pipe -ggdb -g -Wall" xserver doesn't crash but just freezes and in gdb produces this backtrace.

Lots of changes to glamor in the last 3+ years, please reopen if you still see this with current releases.
