Hello! I've logic pro 9 and i usually work with heavy projects (a lot of instrument tracks and plugin) and sometimes in the main window of logic i see artifact for example i can't scroll left or right the arrangement window...Why? It's because of the weight of the project or probably my GPU cannot work with so much data? Thanks
