Cubase 13 screen blackout

Hi, i’ve been running cubase 12 using 2 monitors with no probelms, now after upgrading to cubase 13 i am getting screen blackouts on the mixer screen, the screen then slowly redraws. Cubase still runs ok while this is happening. So does anyone know if v13 is more of a strain on the graphics than v12? And will i need to look at a more powerfull graphics setup?

System specs?

hi, i should have put the specs up
i9-13900 3.00ghz
64gb ddr5
win 11 pro
graphics card geforce gt710 running 2 monitors display resolution 1920x1080
the only change i am aware of is moving up to cub 13 from cub 12
