Sad to hear it. Yes this is a common issue. S22 users also got this green line and white lines. It occurs when the display get very hot. When using 120HZ it's high. I recommend you to only use 60HZ because it will reduce getting future lines in the display. If you only got your device from a Samsung Authorised centre just message and see whether you can get a free screen replacement. Other than that you will need to pay the full amount to put a new display sadly.
