Artboard View turn to CPU preview and greyed out while placing grayscale image in the artboard and we can't change to GPU Preview, and the document never preview back to GPU preview at any instances.
Note:
No issues while converting the image from cmyk to grayscale in illustrator but while place as a link file we facing this issue.

Probably intended. For GPU accelerated stuff there is no real greyscale mode and likely this would require some trickery to expand it back to RGB for display purposes, which may simply not be implemented currently.

Hi Mylenium,
We don't have these type of issues with 2020 version or before that only with 2021 version.

Hi there,
Thanks for reaching out. Would it be possible for you to share the file? You may upload the file on Creative cloud and share the link with us. You may share a small video of your workflow as well. I'll be happy to look into it.

I don't have any problems with grayscale images and GPU preview, linked or embedded, place in RGB or CMYK documents, the document stays in GPU Preview mode. I don't think this is expected behaviour.
