Blend Object snapping objects to random directions and cancelling CTRL+Z operations.

[valencygraphics]

I don't even know how to describe this, but I'll attempt to. Please look at the video included.

I make a blend between two objects. I isolate and edit the blend object directly. I move one of the objects to where I want it to be. The object snaps to a random point beyond where it should go. If I hit CTRL+Z, it will go to the new placement that I originally wanted. CTRL+Z is now reset, so any edits made before this point cannot be undone. You cannot go back any further.

Basic Troubleshooting:
Snapping has been turned off in all instances (all known snapping).
This is in a new document on a newly opened Illustrator.

Hello @valencygraphics,

I'm sorry to hear about your experience. Would you mind trying to run Illustrator under a different administrator account (Windows) and checking if it helps? Also, try running Illustrator under Safe Mode (Windows) and share your observations.

Looking forward to hearing from you.

After a fun boot loop with safe mode and almost having to reset my entire PC (thank you), I can confirm:

This happens regardless of what mode I am in. Solutions I tried:

- Resetting preferences.
- Running as Administrator
- Running Diagnostics (For Windows users, you end the Illustrator task via Task Manager while it's loading, then restart the program. This gives you two options: "Run Diagnostics" or "Launch Illustrator")
- Safe Mode enabled with/without Networking, plus all of the above.

Anything else I can do as a normal user and not as a beta tester/PC repair genius? I've tried to do my due diligence and I know most people don't, but this is just a basic feature in the program.

I'm going to appeal to Adobe here:

Please don't sweep this under the rug. This is a major bug. This did not happen months ago, but I noticed some weird movement bugs with shapes within the past several updates:

- Rotating an object resulting in the object preview getting pushed over to the right or left the more I try to rotate it.
- Objects not snapping properly when snapping is enabled, causing me to have to check and recheck canvas objects or alignment constantly anymore.
- And similar to this particular issue, there have been several times that objects moved of their own accord based on no grid and no snapping enabled before. Luckily, those were solved with a quick restart usually, or within one patch.

I just want to work on my files and get my paycheck instead of playing IT to problems that are not caused by my own incompetence.

This issue is now reproduced and reported on UserVoice here: https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/50474643-super-...

TL;DR: This is a Real-Time Preview issue. If you turn it off for the time being, it will revert to normal behavior. It spams the Undo action which fills up the History queue with preview on.

Valencygraphics,

as per your description and as also shown in your video, I can reproduce the misbehaviour in Illustrator 29.8.1.

I'd say it is obviously a bug.

I had an opportunity to test on both 29.6 and 29.8.1 today as I just updated. It works as expected in 29.6, but as the thread describes in 29.8.1.

I don't have time right now to find a logic to it, but it seems to be any blend that has one object inside another, using specified steps.

[Kurt Gold]

As far as I can see, all Spacing options are affected, not only specified steps.

It also occurs with objects that are not inside of other (closed) paths.

Isolation mode seems to be crucial to trigger the problem sometimes, although it also may happen in non-isolated mode.

Pretty weird and probably not easy to fix.

I made a few smooth blends of objects from one point to another that seemed unaffected, whereas blends made as the OP did were affected straight away -- but it's easy to get led astray by bugs.

Hi everyone,

Thanks a lot for the detailed report. I'm checking this with the product team and will update the thread once I have more information from them.

Appreciate your patience!
