I'm on a TCL 6 Series 55R615. In game mode there is screen tearing at the top couple inches of the screen and it's really distracting. It only does it while playing my PS3 and PS2 (I think. I haven't checked again in a while). PS4 works perfectly fine. It's when I'm playing lower resolution games that it does this. I used to work around this by flipping Game Mode off and on again. But after the 10.5.0 update that method no longer works. Is there a way to set it back to an older version? I'm never getting a TCL again.
