Well before you get too upset, let me assure you that the cores do work as I am using them in a few projects now. They do have their caveats but they do work.
One block I'm not familiar with is the Test Pattern block. What do you have it configured to generate?
What is your Video Output Format?
Do you have the scaler set up for dynamic reconfiguration? This is a bug I found in 7.2. If I didn't enable the control port on the scaler, It would do something similar to what your mentioning like displaying the image multiple times across the width of the frame. You don't necessarily have to reconfigure it, it just has to be enabled.
Your last mentioned scheme is the one you should use:
Test Pattern -> Scaler -> Frame Buffer -> Mixer -> Video Out
Test Pattern -----------------------------^

I wouldn't say that I'm getting upset - I've actually seen some IP running elsewhere - just wondering what I'm missing here! :confused:
The Test Pattern generator is configured to output 640x480.
The scaler has the control port enabled, and when set to 640x480 it works, scaling to anything else eg. 320x240 results in distorted display as I described.
Video output is 640x480.
To re-iterate with more detail, I have...
2x Test Pattern, hard configured to 640x480
1x Scaler, control port enabled, nearest-neighbour, max 640x480.
1x Mixer, 2 layers, control port enabled, no alpha blending, 640x480 output.
1x frame buffer, max 640x480 hard-wired, no control.
1x clocked video output, no control, 640x480.
Thanks for your repsonses,
