Hi,
I am trying to use v3dfx (Graphics SDK version 4.05.00.01) to display video on the primary HDMI output of a DM8168. I have noticed some issues similar to image tearing in both the v3dfx demo application and our own software.
I see two specific artifacts in the displayed video:
- A vertical line down the center of every frame.
- Horizontal sections in some images that appear to contain data from other images.
I have also seen some rather disturbing output on the linux console from time to time such as:

This output does not cause the demo application to crash but I do notice a pause in the video.
I wonder if anyone has seen such issues and if there are any solutions?
Thanks, Steve
