Regression in HL2: http://ivan.ivg2.net/scr.png
Screen is almost completely white - no textures.

New messages (maybe?):

can you provide more traces (all CreateSurface related traces: context errors, 
glx errors, ...) ?

Hi,

The reason for CreateSurface failure is that it runs out of memory... 
I think this used to occur before the patch, and I just didn't notice
it - Oliver said it creates surfaces until it runs out of memory. 
If trace is enabled, it shows the memory going down until:
WARN("Out of 'bogus' video memory\n");

That still doesn't explain the white screen, however - that's a pbuffer
related regression. There are no FIXME messages that I haven't 
seen before - and the trace is 90 MB large, and I don't know what to
look for. I do _not_ see a trace saying "Error in setting current
context".

I expect this is caused by states not being in sync between the pbuffer and old buffer, or
textures not being loaded properly... I've just sent in a patch that should correct the latter.

I'll change those to warns once I'm sure that memory management and object tracking is working
properly, creating the texture and surface failed because there wasn't enough bogus memory.
Halflife uses this to guestamate how much memory the graphics card has.

Re-tested HL2 today, pbuffer white screen regression is gone.
