I switched to the Xorg radeon driver which has 16 bpp support(the 2nd column shows 16 now), and made sure that hl runs with 16bpp, but the error still occurs.
Yes it don't work, because you speak about frame buffer (named Color buffer on traces) when you speak about 16bpp. I spoke about depth buffer
Good, thanks for explaining this to me. I mixed the two buffers. Well, HL doesn't offer any depth buffer setting. There's only one console command, "gl_zmax", which is supposed to set the maximum depth buffer size. The default is 4096, and changing this value has no effect on the error.(HL still tries to get a 32 bit depth buffer)
I sort of fixed the problem for me by forcing the depth buffer to 24 bit in dlls/x11drv/opengl.c, but I understand that this is not a real solution. Is there any chance for a better fix? I have no chance to fix this in the game nor in the video driver
