I hope im not too early but thinks I have fixed issue.
It seems possibly the mouse. I don’t use the mouse but physically got the mouse and moved it to the extreme of window and seems like its all quiet now.
Sorry for any inconvenience.

Far beyond the Shrouded hours of dawn
Through the mist Of daybreak I was borne
But the day was Clouded still by night
Leaving me in the land of no light
