Flickering cursor icon and Unresponsiveness (High Sierra 10.13.4)
Got a new Mac running 10.13.4, installed adobe CC completely fresh. Illustrator is very slow, often comes to a complete stall / irresponsive, and I have to constantly restart the application. And even after the restart, it is still very slow. I turned off everything, including the GPU performance and other things it didn't help at all. The cursor flickers for several tools. It has become very unuseable and drag the time I normally would be able to finish a project by 2x at least.
Can you please check if Dictation is on your MAC. We are aware of an issue where Dictation software was interfering.
If this does not work, please get in touch with us at any of the other support channels – https://helpx.adobe.com/support.html . Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.
