Illustrator CC (22.0.1) Mac - changes pointer acceleration when on GPU Performance

[danadanamania]

This one's a bit infuriating.

Before going back to work in mid January, I've updated all the CC apps I use regularly (Illo, Indesign, PS and Acrobat) to give them a good solid run before doing the work upgrade.

Things look good except for the current Illustrator CC, which changes my pointer acceleration settings when GPU performance is ticked on. It's either a slightly slower acceleration setting or a lag, but it's enough that I never quite reach buttons/tools/points that I'm aiming for. No other app does it - PS and Indesign are both fine.

I can turn off GPU performance reasonably quickly with command-E to toggle GPU Preview/Preview on CPU, but that loses animated zoom and hand scrolling bogs down in CPU mode. It's just leading to serious frustration as I work.

Any obvious fixes? Out of the three main apps I use I'm the weakest with Illustrator experience so I may be missing something obvious.

I'm on a Retina iMac 5K Late 2015, running High Sierra 10.13.2 with 16GB RAM and Radeon R9/M395X 4GB, and an internal SSD.

Sorry don't have the full solution for this one.

However I have a feeling this may be to do with the High Sierra update, did you upgrade to High Sierra around the same point as the other CC apps?

There are some known issues with illustrator and High Sierra that sound similar to yours which are also fixed when you disable GPU acceleration. They mention disabling it thought it were a 'fix' which is crazy as GPU zoom panning etc. is a huge part of using Illustrator on these machines and everything is super slow if you disable it.

I am holding fire upgrading High Sierra and all my adobe CC apps until they can confirm that these issues are all fixed, but it's been radio silence on the issue since November.  Perhaps I have not found the correct update/news page though so if anyone more in the know could advise the current state of Illustrator/Indesign running with High Sierra and if all the bugs are now officially fixed, particularly the one mentioned above that would be super. Adobe have had the developer versions of high sierra for ages before it's launch and still months after launch afaik it's still not fully fixed.

I upgraded my home machine (essentially the test machine for future work upgrades) to High Sierra the day it came out. previous CC versions didn't have noticeable issues with HS that I noticed - though I've read about occasional 2-3 second delays with GPU acceleration turned on with High Sierra and the previous Illustrator, but it never arose on my machine.

I did upgrade to the newest Photoshop CC as soon as it came out; it's the main app I use personally so I want to explore it first out of curiosity. I suspect Adobe have a special interest in working on Photoshop's cursor 'feel' more than the other apps as it's used to paint so much more than the others - and indeed here it solved a bunch of Wacom jitter issues I'd had for years.

Thanks for the link - gives me confidence that something is happening behind the scenes, even if slowly.

I've had a largish Indesign project I've had to work on for the last two days too, and I noticed that like Illustrator there's *is* a very slight pointer lag that also disappears with the GPU off. It's maybe 1/4 of what I see in Illo though, only enough to perceive after a while but not really affect how I work.
