The call at 297 is also the same case.

Graphics driver issue.

How is it that it works most of the time, and fails some of the time then? D:
If it's really a graphics driver issue, then I don't know where to start.

What graphics card are you using??

"ATI Mobility Radeon HD 3400 series"

this is indeed a graphical driver issue, however im not sure why or what is wrong

i got that error in Timesplitters 2 when i shoot(GF6200 with latest drivers)
while others who have the latest drivers dont.

want to point out btw, that this indeed failed on my GF6200 & P4 2,4Ghz (no HT)
while it works fine on my P4 3Ghz(with HT) and GF8600 (same driver version)

i have no clue
it could be lack of 2.1 (the Geforce 6200 has 2.0), it could be nvidia's fault for
horrible opengl , it could be the drivers or it could be dolphin handing over invalid
data that some cards can't handle :/
the only way to know for sure is tests

Can this be closed?

ill test it again soon :)

Recently I havn't been getting this problem at all.
