ThinkPad t480 Big Sur + Open Core full screen videos make screen goes black.

Hello guys,

I am new o hackintosh world thanks to the help one of the guys from group in my country I have successfully install Big Sur. At least that's what I was thinking till now.

I have noticed that when I watch movie or anything on full screen after around few min sometimes few seconds from bottom comes rose/purple bar that growing and then the screen turn off, I can hear anything etc so the laptop is working but to bring image back I have to restart it.

I have tried to change cursor size it helps at the beginning but then problem comes back.
