Strange video noise with "Quickcam Pro USB" and TrackerCam 3.01?

We have a QuickCam Pro (older model), attached to an IBM Netfinity server
with built-in S3 video card.


The camera works in all modes including 640x480, with the software from
Logitech, and with third-party software from other vendors, with no "noise".
Under TrackerCam 3.0 or 3.01, the display always has "noise". The noise does
not appear in saved frames, only on the display.


If set to size "2" (176x144), there is a small white horizontal stripe on
right side of one of the first scan lines. At size 3 and above, there is
continuous video noise throughout the displayed image, primarily seen as two
fast-moving vertical stripes of video "noise", in the center and far-right
side of the displayed video window.


The PC is an IBM Netfinity with only the on-board S3 (Trio3D) video card.
Is this "noise" an expected effect of using the on-board video card in this
PC?
