Hello, question to the Xperts:
my system is an ASUS A7V 266 E with 256 MB DDR RAM AMD t-bird 1.333 GH MSI 8851 (GeForce3 TI200 based) Debian Linux with kernel 2.4.18 XFree86 4.2.0 binary release with nvidia drivers (kernel module + GLX) 1.0-2960 NO overclocking. I see "random" false triangles flashing during glxgears (original binary!), and at random occasions (not at every startup of my app.) stationary (!) false triangles in an glut3.7 -based OpenGL application. For the OpenGL application, this seems to be correlated to drawing identical graphics at the identical location (the data im visualizing happen to be that way...), so maybe it's Z-buffer related?? (wild guess...). For glxgears, the effect is sometimes worse and sometimes hardly visible. Again, the artifacts seem to be originating from the (virtual) center of the bottom left gear - this is very often one vertex of the flashing triangles. BTW, for glxgears, with the effect hardly visible, I get a rating of ~2400 fps at default window size, dropping down to ~1800 fps when the effect is strong. For glxgears, the effect is either present from the start, or not. So far, I haven't observed it "developping" over time. For OpenGL, this may be absent from the start, but often appears after a while. The app is double-buffered. I checked the nvidia news forum, but there were no linux/XFree related posts. I would like to provide a screenshot, but am embarrassed to say that I don't know how to make one under Linux... 8-( Any insights will be greatly appreciated.
