Welcome to Android Central! Does it also happen in Safe Mode? https://safemodewiki.com/how-to-enable-safe-mode-on-huawei-p20-pro/

Hi, welcome to AC!
If its still happening in safe mode then try factory reset or might be a software glitch

If it persists after a factory reset, then it could also be a hardware fault with the screen or one of its connections. You'd have to bring it to a repair shop (or contact Huawei, if it's still under warranty).

Yes tried a factory reset and still the same and warranty has ran out now

Something wrong with screen if you have to warm it up , get a quote from a repair shop , see if its worth to fix .
