Adobe and Wacom have recently identified a problem with some Wacom drivers that can impair After Effects performance.
If you’re having problems with After Effects being sluggish, and you use a Wacom tablet, read this thread on the After Effects user-to-user forum and the pages and threads that it points to.
If you have bugs to report or additional information to provide, please use the bug-report/feature-request form. Those submissions are read directly by the After Effects engineering team. Leaving comments on this blog is not the most effective way to communicate directly with the After Effects engineering team.
