I'm using Photoshop 22.4.1 on several Macs and I've noticed a bug easily reproductible with the vector paths:
First, in the Preference Pane/Performances, I uncheck "Use a graphic processor" and relaunch Photoshop.
Then I draw a simple vector path with the Pen tool. When I want to select or unselect the path with a Path selection tools (black or white arrows), it's almost impossible to select or modify or unselect the path or a vector. It's like the display is frozen or unresponsive (sometimes it works, sometimes it doesn't).
OK, I can check 'Use a graphic processor" on some Mac and work normally BUT in my classroom, all my Macs can't enable the graphic processor (my iMac with Catalina are too old) so I can't show to my student how to modify a vector path.
It's very annoying…
Can you try and confirm the bug ? And report the bug to Adobe, as I'm not very fluent in English (I'm french speaking) ?
