Currently I am using Windows 10 pro 20H2, RTX3090 with latest Nvida Studio driver and Photoshop 2021. I found that after using the plugin e.g. color efex, to manipulate the photo and exit back to the workspace. The photo is no longer able to use the GPU resources, for example, zooming in/out the photo and that photo would be switched to use CPU resources. And sometimes, there is strange palette generated on the photo workspace window.
It is reproduce-able, and it is normal for using GPU resources and camera raw, once I triggered the nik collection plugin and go back to workspace, it happens caption behaviour.
