Aseprite laggy on full version, smooth on trial version

Hello! I recently downloaded Aseprite and I came across a huge problem. When using the full version, everything was fine until I moved my cursor into the canvas or color palette. The cursor was lagging and making the art creation process extremely difficult. I downloaded the same version onto my laptop, and it was smooth. I then tried the free trial out, and it worked smoothly on both computers.

Can someone please help me with this issue?
