Bug 27469

Cannot describe this so precisely, as in my earlier reports - but maybe it can be of some use to improve Mesa3D library:

I noticed problems with two games:

1. "Polynomial" (demo for Linux) http://dmytry.pandromeda.com/games/

After start (no graphics shown), there is crash. The last lines of its messages are:

(3169) last ShapeMaker::Update()
(545) TestTextureFrameBuffer::TestTextureFrameBuffer
glGenTextures: success
glBindTexture: success

I contacted the author, and he answered:

"Unfortunately I think it cannot be played on mesa dri drivers - those are beta and it is very difficult to make opensource drivers for graphics hardware, even with some hardware documentation available. Judging by stacktrace, the crash happens outside my code, very little I can do."

2. CG Madness 1.2.2    http://cgmadness.sourceforge.net/

Compiled with just "make" it seems to be built properly, but right after start (no graphics shown) it freezes the system for good (even "Magic SysReq" doesn't work). On my hardware it's complaining (right before the lock-up) about lack of "framebuffer", and that there's no "OpenGL 2.0 shader" - but I'm not sure, is it related to following crash; in my opinion it should run with somewhat poorer look.

AFAIR (but I'm not 100% sure) I was playing the game without problems when I was using Mesa 7.5.1.


Like before: both games tested using Kernel 2.6.32.10, Glibc 2.10.1, Gobolinux 0.14 (32-bit), Mesa 7.8, Xorg 7.5, X-Server 1.7.6, IceWM 1.2.37, Pentium III/750, old mobo Intel BX-based, ATI Technologies Inc RV280 [Radeon 9200 PRO]
