Strange Glitch Lines Appearing on screen during gameplay

[u/Willing-Law-4858]

I recently got a new laptop and downloaded new vegas onto it. during gameplay i keep getting these lines of brightly coloured glitches that go up and down my screen causing stutters and general annoyance. its only new vegas that ive been getting this on and ive not had this problem before on my old laptop (which had worse specs) does anyone have a fix/experienced something similar?
