If Win 10 is installed [https://www.windowscentral.com/generate-battery-report-windows-10|create a Win 10 battery report] to check the status of the battery. I realize that you said that it works OK when on battery power only, but power problems can be caused by a lot of things and they may have to be eliminated one by one. In this case maybe the battery actually faulty and is demanding too much power from the charger to the detriment of the rest of the hardware, whereas when it is on its' own it only supplies power to the laptop and there is no power from the charger.

Try starting the laptop in [https://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10/|safe mode] and check if the problem is there when the charger is connected to the laptop. If not then it is a driver problem, as in safe mode only basic generic Windows drivers are installed and not hardware specific drivers. The screen will look different because of this but it should work OK.
