Why is my piano roll fully grey?

[Sloth Net]

i have had this issue for a while. its super hard to see some notes and impossible to copy and place them in the right spot. ive never found out how to remove it. but i remember there was a time where this wasnt there. ive been looking through the settings but i cant find anything. any advice is appreciated
