Im having an weird bug on my MacBook Pro. When I start the machine, the dock have some graphic lag, the same when I open and close windows.

The solution is simple, just open the AutoCAD and close it and the bug is gone.

The same if I open AutoDesk Maya or other similar 3D program. My question where is not how to fix it, but why it happens.

Its like Mavericks on the start thinks: Well you can only use a little memory of the graphic card! But if i open AutoCad, its like: Oh you are opening AutoCad so its better starting boosting the graphic card and giving you more memory.

I bet there is something that is forcing Mavericks to think like this.

Any help is welcome! =)
