Part of an object's position is shifted with no distortion effects. Moving/undoing move resets position correctly
This was a devastating glitch for us. I've seen this happen before sporadically but I have no idea what causes it or how to catch it. If anyone else has seen this and/or knows a solution to catch issues like this, please let me know. There were no effects or special attributes applied to the artwork in the appearance panel

...and I can’t reproduce it. It may be a specific bug that affects only Macs, because I am on Windows. Needs testing.

You are correct, this does appear to be a GPU issue in relation to using the align tool. Huge bummer because using CPU slows down our workflow significantly. Is there any way to fix this so GPU mode can work? 2020 iMack Retina 5K with AMD Radeon Pro 5500 XT 8 GB running macOS Big Sur 11.6.4
1. With this file open, set the alignment panel to align to the artboard.
2. Select the group and align to center horizontally and vertically with the align panel.
3. Undo twice to revert to the original position.
4. On the second undo action, you’ll find that some of the artwork doesn’t move with the rest on the last undo action. Moving the group manually after this magically moves the artwork into the correct position.
Manually moving the object without using the align tool and then undoing the move transformation does not cause this problem. This is why I believe the issue may be related to the align tool.
Michael, it feels like a rendering bug.
Please share the fil for the team to test, provide more info about your GPU, and try to disable it in Ai’s preferences as a workaround.
