            Bug ID: 92959
           Summary: [NV1F celcius GeForce4 MX] Rendering artifacts, screen
                    corruption, system reset.
           Product: Mesa
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org

dmesg after booting.

The system displays rendering artifacts. 

The first ones to appear are thin lines flashing around on the lower half of
the screen. Once a single (or multiple) program(s) is opened which use Opengl
the screen will become partially distorted  and usually (but not always) in the
lower half area. 

Typical glitches seem to be made up of fragments of what is shown on screen.

In most cases the computer needs a reboot to get back to a nearly clean
desktop.

It gets triggered, or rather worsened by programs which use Opengl.

Vlc media player, while using the Xvideo output(XCB), will only suffer the
anoying twitching glitch on the lower part of the screen, which also affects
the desktop.

This happened twice and will not be tested again for the sake of my hardware ;
The system will reset without warning if running Opengl video, games, programs
in full screen for prolonged times.
