BEGIN_NV04(push, NV30_3D(CLEAR_DEPTH_VALUE), 3); and the valgrind--mmt
output is
0xcfd8c in line 281 of the valgrind-mmt's output file.
As I can see there is 215 lines (from 66 to 280) of valgrind--mmt that I do

No window decorations for simple glut app on compiz/aiglx?
...ks as expected when compiz isn't the WM.
Can anyone else confirm they see this too?
Any suggestions on how to fix this up?
Thanks much,
Sean
P.S. compiled with -lGL -lglut and using r300 driver.
#include <GL/glut.h>
void DrawScene(void)
{
glClearColor(0.5, 0.0, 0.0, 0.0);
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0.0, 0.1, 1.0);
glutSolidTeapot(0.6);
glFlush();
}
int main(int argc, char *argv[])
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);
glutCreateWindow(argv[0]);
glutDisplayFunc(DrawScene);
glutMainLoop();
return 0;
}
