Hi All, I believe I have found the cause of this issue, however the solution (until Microsoft Fixes it) does require you to live with a different resolution on your laptop's built in display or use a secondary monitor for your SmartArt to work.
Just as a reminder I am running a 14" MacBook Pro M4 and my (default) resolution is set to 1512 x 892 which from my understanding is optimized for visual clarity and readability.
If you change the display setting to 1920 x 1200 ..... the issues compltely dissapears! its like magic. Note to test this please close PPT before changing the resolution on the display.
I have not tried this at the higher settings, and for now will need to resort to running PPT on my secondary display when I am in need of this functionality.
Please let me know if this works for you or if there is a clearer way of explaining it to others.
PS. I like my 1512 x 892 settings and will have to make do until MS fixes this issue in upcoming updates to the Office Suite.
