Without patch on ULE kernel my UP 933Mhz PIII
with nvidia card:
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce2 MX/AGP/SSE
OpenGL version string: 1.4.0 NVIDIA 43.65
and x11/nvidia-driver installed

GLMatrix screensaver blinks too match instead of smooth 3D moving, there
was no such effect with native scheduler.

Problem exist with and without other load on the box.

Should I try patch ?
