I bought Imac M1 yesterday and started to splitting view and worked on that for an hour. When I closed all windows, I realised that there was a single vertical line right at the place where the view had been divided. I've worked that way on my Macbook and it has never happened before. Don't know what happened to my new Imac...
If is just a faint line, then it is most likely image persistence and it will fade over time.

Restart in Safe Mode per the directions in Use Safe Mode to isolate issues with your Mac and then restart normally and retest.
Is it related to software or hardware issue?
it's a faint line and yeah, it actually disappeared after 10 minutes.
Vertical line appears after splitting view.
