I am using Video Test Pattern Generator v7.0 to debug. When ENABLE_INPUT (0x0098) Register is set to 1, external video will appear video bias after this IP output, and each offset position is different.Configuration auto reset is also useless.
I am very anxious, I hope to help me answer！

What resivion of the TPG v7.0 (or what vivado version) are you using?
Did you try to see if it was happening in simulation? If you need some reference for simulation you can check my Video Beginner Series 3: RTL simulation with input from an image file (PPM) for an example of inputing an image file and my Video Beginner Series 5: Saving simulation outputs to an image file (PPM) for saving the output of the TPG in an image file. You would need to merge both and enable the path-through feature of the TPG.

Thank you for your reply!
I am using vivado 2015.4,I found this problem during the hardware debugging process.

Note that 2015.x are not supported anymore. We only support 2018.x and 2019.x versions.
However I am not aware of any known issue. Again I suggest you to try in simulation.
Also you need to make sure you are resetting the TPG each time there is a input change.

Do you have any update on this? Did you make any progress?
