Here is what happens, try to replicate it:

1. The document has a Layer 1 and it has a sublayer — Layer 2, which has one rectangle in it
2. If you select the Layer 1, the Make/Release Clipping mask button enables — click it
3. Notice that Ai underlines both Layer 2 AND <Rectangle>, as if they are both are clipping masks
4. If you click it again, everything is OK. But instead, select the Layer 2 and click the button after
5. See how Ai still shows Layer 2 underlined (bug #1)
6. Select a circle and see how the underline vanishes, and only <Rectangle> is now considered to be a mask
7. You can select circles and everything stays as it was, until you move one — then suddenly the canvas gets updated and all shapes get rendered as unclipped (bug #2). Sometimes it happens partially, and it seems to be unrelated to CPU/GPU view mode
8. Undo everything and clip again
9. Hide the rectangle and see how all circles get visibly unclipped — that is OK
10. Now toggle visibility of the Layer 2 instead — something changes, but circles are still clipped
11. Hide Layer 2 and drag one of the circles — boom, they are unclipped again (bug #3)

Sublayers are broken and this is why I avoid using them.
Please fix.

When a compound shape (not a compound path, but a live result of any Pathfinder operation) is used as a clipping mask, Illustrator does not display edges for the resulting objects.

1. View > Hide Bounding Box (for clarity, to see the issue better)
2. Draw anything
3. Create two intersecting rectangles
4. Select these two rectangles, hold Alt and click Unite in Pathfinder panel to get a live compound shape
5. Select both the compound shape and the art below
6. Object > Clipping Mask > Make

The resulting object has no edges drawn and can’t be seen as selected, until you enable the bounding box. There is no reason to not display the edges for it, except for the carelessness Adobe has about maintaining Illustrator a solid enough tool.

MacBook Pro (Retina, 15-inch, Mid 2015)
Just recently install the macOS Monterey
Using the newest version of Illustrator 2022

The clipping mask doesn't work after I zoom in or zoom out.
It shows what is inside the clipping mask with different shapes randomly every time just like the images below. I have to move around the image to get the original shape of the clipping mask.

It works quite well in Illustrator 2018 actually.
But the Illustrator 2018 version seems can not be downloaded anymore.

I think people should be allowed to download the older version which they found most stable and familiar. Otherwise, we can only work with errors while waiting for them to be fixed.

I hope it will be taken into the consideration, thanks.
