Live Paint Dead
Wow, I haven't seen AI get this slow and bad at basic vector work in years! (Just might be way too bloated.) Had to delete latest version 25.1 and go backwards just to get my day job done on time.
Thanks for reporting the issue , Illustrator team really appreciate this.
Unfortunately we are not able to reproduce this issue. Could you kindly provide the following information to help us nail this down :
1. Machine details which can be found by :
MAC : Choose Apple menu > About This Mac.
WIN : Go to settings and Click on System and Click on About . In Windows Specifications , machine details can be found .
2. Kindly provide a short recording and Test file(Via File→Package) with some steps with which you are facing the issue and share with us in a zip file on ShareWithAI@adobe.com .
Also , kindly let us know with which previous version of illustrator it is running fine on your system .
Thanks and Regards ,
Primary cause was that Windows was secretly downloading and installing a major update in the background. This manifested in terrible performance in Adobe Illustrator.
