I'm running the latest version of LPX on a MacPro (10.10.1), 16 gigs of RAM, 1 gig ATI card. The application runs well, except when I attempt to use the Marquee tool to make selections directly on a region (in a track) or in the "Track" Editor.
After making a few smooth selections, the subsequent selections become erratic and very choppy. When you drag through the section area, there's a hesitation before the selection appears. This happens more frequently right after playback when stopping or pausing.
Setting the Left Click Tool or the Command - Click Tool to Marquee eventually replicates the same erratic behavior after a certain amount of selections.The project is a basic test project with only a few tracks and a limited amount of clips.
Is there anything that I can do to troubleshoot/correct this? I also run Pro Tools 11 and it runs well with no issues.
Thanks.
