Unidentified black box in IllustratorHi!

I need help solving the problem of this unidentified black box that shows up whenever I am in Illustrator 2019. I have been using Illustrator 2018 for awhile until this last update, which now the 2018 version is disappeared off my computer. Can someone help me get rid of this black box.

I have tried escape key, rebooting, updating...I can't click on it (nothing happens when I do) or highlighting it.

Thanks for anyone's help.

Hi Tara,

Thanks for reaching out. This definitely looks like a Display issue. Please turn off GPU performance (Illustrator/ Edit > Preferences > Performance > Uncheck GPU Performance) from Illustrator preferences and let us know how it works. 

Regards,

Hi,

I do not have the option of checking/unchecking GPU Performance.

Would you know why that is?

Thanks
