which half? horizontal or vertical
I suspect the display has a fault...
You can plug into an external monitor and compare your results— if you see the same issue there points to GPU.
No issue externally, points to Display.
In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
