x=0 pixels duplicated on hdmi out #470

Open CarlFK opened 5 years ago

CarlFK commented 5 years ago

looks like all the pixels are shifted to the right, there is a extra copy of the left side, and the right side is lostjj

the error is not present in the encoder output, so I guess it is correct in the frame buffer, but the buffer to hdmi is off.

I see it in both Atlys and Opsis, both of these revs (I didn't go back further)

git describe: v0.0.4-485-g5fbb99d and git describe: v0.0.3-1045-gccb30b9-dirty

The pictures below:

bw diagonal lines - dupe pixels are easy to see. I can see them on my LCD monitor too.

ellipse:

the upper 1/2 is the original, the lower half what is captured from a 2nd hdmi2usb device.

Can you be more specific about "left row"? Do you mean x=0?

CarlFK commented 5 years ago

Yes. x=0.
