Random offset of blue vs Red/green component on screen #88

Open mikerr opened 10 months ago

I'm getting a random offset of blue from the red/green channels on screen.

After each reset it can vary from perfect/no separation to the blue channel being up to 20 pixels to the left

See example screenshot: screenshot

This is with the widescreen python image pimoroni-picovision-widescreen-v1.0.2-micropython.uf2 , and the code at https://github.com/mikerr/picoVision/tree/main/willy

Thanks, I was able to reproduce this after a few stop/starts. I see a yellow bar down the left hand side of the screen - so I suspect blue is actually in the right place and it is red and green that are somehow wrong. Additionally in my repro red is offset to the left one pixel (looks like not a doubled pixel!) from green.
