Hi shtl,
Make sure you test this as well on a freshly started system without having any other apps running, and surely not a web-browser open. 😉
I tested it here with a MBP M1 16" and running an XDR 32" display. 2024.5 as well, OS 14.4.1
I have created a plane with 100x100 segments, two layers, and a 4096x4096 image.
Painted with and without projection, detached, moved, etc.
All with no delay.
In other words, sorry that you have to experience that, and please get in touch with tech Support:

Fingers crossed, it will work in no time.
Cheers
