My cursor constantly flickers and sputters in Illustrator. I've seen multiple posts similar to mine and the solution always seems to be "uninstall 3rd party web companion programs" like Lavasoft, but I don't have any of them installed.
Has there been any solution to this, or do I just have to suffer through it? Apparently this has been an unresolved issue for over 6 years.
Sorry to hear about your experience. Would you mind sharing the version of the Illustrator? Have you tried using the app while disabling GPU Performance(Preferences > Performance)? Additionally, please try suggestions given on this community post. Let us know how it goes.
