Ubuntu + Blending = Crash

I recently installed BZFlag 2.0.13 on Ubuntu 10.04 (Linux 2.6.32-24), however if I turn on the "Blending" option, after some seconds the game crashes. This doesn't happen if I turn the setting off.

Sounds like it is probably a video driver issue

Did you compile from source? Or is this the version from PlayDeb.net?

Okay, so it isn't 2.0.16 then? And that certainly looks like an issue with your video driver. Does dmesg have more information?

This is kernel bug and is fixed with kernel commits in 2.6.34-rc1:
7a9f0dd9c49425e2b0e39ada4757bc7a38c84873 drm: Add generic multipart buffer.
b4fe945405e477cded91772b4fec854705443dd5 drm/radeon: Fix memory
allocation failures in the preKMS command stream checking.
55a5cb5d594c18b3147a2288b00ea359c1a38cf8 drm/radeon: Fix printf type
warning in 64bit system.
So maybe see if there's a newer kernel version?

Ubuntu ships with a decent update tool, so you should use it in case you were not compiling the driver from original source. Then you should do both: Updating the kernel and recompile the latest driver version to be 100% suitable for your new kernel.
Additionally:

This indicates that you are not running on full 3D accelleration, you may need to edit your x.org configuration by hand to get it to pick the correct driver.

What part of that indicates they are not using 3D acceleration? Looks like it's using the DRI driver for their ATI card to me.

From my experience Mesa isn't the optimate solution for an ATi card. If the proprietary ATi driver loaded fine it shows something like "ATi Radeon ..." but my memories might be false, it's been too long when I had those problems. All I remember was that certain things didn't work with Mesa on my Radeon card.

Well, R100 refers to older ATI cards. ATI does not provide Linux drivers for it's older graphics cards. Seems like their site only shows a Linux driver when you pick the Radeon 8500 series or higher.
Also..
http://en.wikipedia.org/wiki/Radeon#Linux
The proprietary Linux drivers could support R200 (Radeon 8500-9200, 9250) chips.
...
In 2009, the Catalyst driver officially dropped support for R500 and older chips, the FOSS driver being deemed stable and complete enough. The last driver release supporting older architectures is Catalyst 9.3.

Edit: Here's a bug reports that relate to this issue. Seems like the one I linked to initially might be a different issue:

With Ubuntu 10.10 and the new kernel, BZFlag crashes just when I minimize it and I reopen it again. IT ALSO crashes with blending on and when I resize the bzflag window. Crazybot players, no more bots.
In debug x2 mode, this is standard output:
- bzdebug.txt
- Standard output
- (1.49 KiB) Downloaded 159 times
and this is standard error:

UPDATE! For some reason, BZFlag is OK with older kernel.

Kernel bug? Seems to be the issue that was identified...

Fix the kernel bug? This is not an issue with BZFlag.

Or use a working kernel.
Or wait for an update.
Or play with crashes but the current kernel.
