Default 4191 and 4349 2d corruption problem

Ok, this one is a fun one...

(screenshot attached, with lots of ugly .jpg compression (sorry about that))

Take just about any program that updates the screen quickly.

e.g.

#include <stdio.h>
int main(int argc, char**argv){
int i;
while(1){
printf("\r");
for(int j=0;j<10;++j) printf("happy happy joy joy ");
printf(" %d",++i);
}
return 1;//keeps compiler happy. Bad compiler!
}

Ok, now run it for a while. Some random amount ot time later, you'll start getting corruption anywhere you move the mouse. The corruption seems to start in the rapidly updating window,
and then can at times go away.

This bug is not apparent in 3123, but IS in 4191.

.. I do lots of GL programming every day with your drivers (I do real-time television special-effects)... and that means that I can be a veritable fountain of bugs. Should I just email them to linux-bugs@nvidia.com, or do you want me to post here first?

Thanks!
