Serious Mouse Lag. I cant do my job

[Forward Motion Medical]

Hi,

I have a some serious mouse lag problems lately while working in Illustrator. I havent changed anything, I've been using the same MacBook Pro and 4k secondary display for the past 3 years and never had a problem. When the mouse is over the toolbars it is fine, but when the cursor is in the working area the mouse lags so bad that the program is unusable...

I've seen this issue brought up on other forms, but so far the only work around is to work on my laptop screen and toss my secondary monitor in the trash This issue needs to be resolved soon... I dont really want to learn Corel Draw...

Ai version 23.0

MacBook Pro

macOS Mojave 10.14

They can login to your system. And they will need to do that in order to check out what exactly is causing the lag.

May be the software engineer at Adobe forgot to fix everything before they release the lastest build. This is the reason why we have AI taking over humans.

It's may 2020 and the problem still here. I have the same issue than you and the solution was closing Ps while using Ai. I am SO FRUSTRATED that I can't even express.

Yes, that's what I've had to do; quit Photoshop to fix the Illustrator mouse lag issue.

Every software update I cross my fingers that they'll fix it. Not yet.

also now bridge gets stuck and reboots my usb? than recovers
