I use a grid in most of my FLA's and I found that, unlike previous versions, Flash CC playback is very slow if the grid is showing. Please fix this bug, it's pretty bad for a 64-bit application in Mac 10.8.
Also even slower if rulers are showing. I hope there is a way to speed this up, it's crucial for my workflow and I'm sure the workflow of other Flash animators.
I'm not able to see this. Is this specific to any content or do you see this for all files on your system?
If yes can you share us the content- XFL/FLA?
