[Directx]

I had the same issue with 8.0.3. It's fixed in 8.0.4. What you're seeing are the highlights for a control surface. Here's what I did to get rid of it: From the main Pro Tools menu go to Setup / Peripherals / MIDI Controllers. Under #1 the Type will probably say "None" (assuming you are not using a control surface). Click the drop-down and just select "None" again. Then click "Okay" to close the Peripheral dialog box. Your highlights should now be gone. You will have to do this each time you start Pro Tools. Doing this in 8.0.3 you will also lose the functionality of your footswitch (if you use one). I would suggest updating to 8.0.4. Hope this helps.
