When using the crop tool on a Win 10 PC with GTX980Ti here with latest Nvidia Drivers (and previous) and ACR 1388 we are getting screen corruption whilst rotating the image to crop. This can be avoided using CPU only, but is slower as the rotating of the RAW to crop is obviously quite a high workload. (Obviously having the legacy crop option available would also have solved this issue, as the image would not need to be able spin..)
Interestingly (or not) this flicker is not recorded by a screengrabber, (Acethinker Screengrabber Pro) - which could be a clue perhaps?
I would suggest this level of flicker/corruption could be a danger for those with photosensitive epilepsy. By the way, it would be great if the topics below included the plugin that this board refers to.

I am not able to replicate this issue on Camera Raw 15.1.1 using Windows 10 21H2 and an nVidia GT970 using driver number 528.24.
You may want to perform a clean reinstall of your nVidia Driver.

Thanks for the prompt reply Rikk, I will (a) try 15.1.1. (I am on 15.3.0.1388) and (b) post in the correct (pre-release) forum. (Driver was a clean install)

First, try disabling GPU in the preferences (Performance). Any better?
If turning OFF the GPU works, it's a GPU bug, and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products. Disable third-party graphics accelerators. Third-party GPU overclocking utilities and haxies aren't supported.
