2915 Demux'd but display looks like GPU issue

See images. This was Demux'd using Doslab's flashing of the GMUX. I've checked and tidied up the LVDS double checked connectivity there and made sure no pins are shorting together. L9010/11 look good. Resisters around GMUX check out. Definitely looks like slightly bad or off connection somewhere. Any thoughts?

Did you flash with correct jed file?
Before reflashing GMUX, did you get boot menu image with good quality?

I have a few of these that I did all at once but I do think the image was good before I bypassed it because I debated leaving the GPU as it was. Try reflashing the GMUX then? I did check to see that the dedicated GPU does not show in system info...

Redo GMUX flash and check the boot menu image.
Don't forget to solder back R8904/11 (which one was removed).
