I have 6 GB ram, I experience the issue if I boot linux as is.
As told above the provided patch doesn't help, and after reading it I don't see
how it could solve anything, but I would be glad to have an explanation for my
understanding.

Using mem=3G or mem=4G, the issue disappears completely even after 4 hours of
World of Warcraft.

I have reproduced the issue with the minimal test case provided on nvnews
forums (see comment #33), it looks like it is related to using a 32bits opengl
program in a 64 bits OS. Even glxgears (32 bits) shows the issue.
For me the issue could be related to the fact that the nvidia driver uses ram
for texture above the 4G if such ram is available, leading to issues when
running in a 32bits userspace.
Anyway it means the 32bits implementation of opengl is faulty on 64bits hosts.
Maybe its just the wrapper, maybe its the driver, but its probably not wine.
