TH8A & weird line on screen

[sparkz]

Hey guys,

Real weird one here. Just got a TH8A & weirdly when in Assetto Corsa in a manual car, & ONLY when in 2nd gear & only on my middle screen, I get a pulsing purple line. I managed to get a pic after a few attempts lol, the line actually flashes on/off

Any ideas

What screen is that, model?

Do you use Content Manager? Do you happen to have button 2 of your shifter mapped to any other function?
