Installed Version 11 recently and we found that if we use the built in print option for any images file (which normally creates a PDF and opens in a new PDF viewer tab) we just get a grey screen. Also the controls at the top do not respond when trying to click on them.
I went back to another 10.4 system and it works just fine, displaying a PDF version of the image.
Tested with multiple image files and from multiple workstations.
