Hello @Jim23946132shhd,
Sorry to hear about this experience. Please provide a few more details like:
- The exact version of the OS and Illustrator
- Since when are you facing this problem?
- Have you turned on any display scaling settings on your computer? If yes, try changing it to the default and check if it helps.
Also, please try changing the UI scaling under User Interface Settings in Illustrator's preferences and let us know how it goes.
Looking forward to hearing from you.
Thanks,
Anubhav
