Two years later ... Apple Mac M2 with OS14, Illustrator 28.0 and the problem still exists ...

This is driving me nuts when I try to align cropped images. It used to work nicely but not now. Please fix it.

When you break a workflow like that you not only drive people nuts but waste hours of their time with unbillable hours. Adding features is ok. I can elect to use them or not. But changing fundamental behaviors that have been in place for decades is just sadistic.

Edges get disabled when you use GPU Preview. Sure there should be a way to view them still without loosing the performance boost.

I've been using Alienware 25 AW2518Hf gaming monitor and it is one of the https://monitormega.com/best-monitor-for-fighting-games/ best fighting games monitors. One of my friends suggested me this monitor to me, it's been a year now I'm using this monitor and I regret nothing. If you want to go with this I'm 100% sure you will not regret it.

Here's a new video showing that, as I suspected and mentioned, it is not Hide Edges. It's a bug.

Here is the file

Toggling Hide Edges looks exactly like your video to me.
Here’s the GIF. What is the difference?

I don't think this was the issue. Restarting the computer and Illustrator fixed the problem.
Also toggling Show/Hide Edges doesn't replicate this issue for me.

It feels like Cmd+H was pressed unintentionally, and Illustrator stopped showing edges to you. Please try to enable them back, with Ctrl+H or via View > Show Edges.
Does it help?

When moving shapes around the artboard, the bounding box disappears. This makes positioning objects with no stroke or fill almost impossible.

Video attached showing behaviour.

I am using Adobe Illustrator for over 10 years and this is such a flaw. I mean I can get used to it, but if another program as Affinity Designer has guides, I will switch soon to that program. Please fix this! Guides are no where to be found while moving paths, shapes etc. this is not good.

I'm surprised there are not more votes on this! please fix

THIS PROBLEM IS DRIVING ME CRAZY.

In order to be able to see my guides as I move them, I must have Real-Time Drawing and Editing off. Surely, this can be fixed so we can take advantage of this feature but still be able to see where we are moving our guides.

@George Williamson, telling people to "get better hardware" is not the solution. That's utterly ridiculous! I have a tower PC with three Nvidia 2080Ti's and the problem affects me just as much as anyone else.

Neither is the solution to "uncheck the Realtime drawing". This is a 'hack' that many people have suggested but fail to realize that in doing so they are disabling a feature that they are paying for. The reason we pay (pricey) subscriptions is to fund the continuous development and improvements. Switching new features off just to save one of the oldest and most fundamental features (guides) is ridiculous.

The Solution that we all need to PUSH adobe in to action is.... "fix the buggy software" !!

Well if it worked before they broke it, "average hardware" seems a bad argument to me. For example my iMac 2019 should be powerful enough to handle this (but I have this bug, too - also on other computers). It is just one of many bugs in Illustrator and if it does not appear on your machine, you are lucky. But don’t tell people to buy new hardware, because Adobe broke their software....

You can Solve it by Doing the following steps:
Go to Illustrator Preferences > Performance and un-check "Real-Time Drawing and Editing."
This happens because of average hardware. Get a better laptop I would say.
