GTX 1660 Ti Screen flickering in game mode and black screen on boot

ok so to get around the back screen on boot I do ctrl+alt+F2 and I login then run

steamos-session-select plasma

steamos-session-select plasma

to get to the desktop I do believe this relates to the screen flickering issue in game mode as I have bazzite set to boot into game mode.
