LrC 10.1.1 on iMac BigSur 11.2 update

Ok I need to make an update here, after doing some further checks the problems I was experiencing with doing crops in the Develop Module is working as I would expect. The zoom in and to 100% is matching with the fit in the display, and the crop issues are also ok.

While in the Library Module the fit mode the display closely matches the display in the Develop Module the 100% zoom display displays with a slightly muted or reduced contrast. See the screen capture. Left is Library fit, the center is Develop fit and the right is Develop 100%.

A while ago I was trying to update my earlier post but I got interrupted by an overseas call from a relative in Canada, which took close to an hour.

The zoom display problem was also evident in the Develop Module.

Also, I experienced problems in the Develop Module while attempting to utilize the crop feature which was causing the system to "hang" for a minute or two to complete a simple edit. Other features I did not check and eventually I reverted my system from LrC 10.1.1 to 10.0 after which things reverted to more stable functions.

The only thing I did after that is to delete and rebuild standard previews. Now that I have upgraded to macOS BigSur 11.2 these problems have gone away.

Just my recollection and thoughts.

At the time I reported my prior problems in the Feedback Forum.

Specifically what display problems? 

There are some on Big Sur reporting a known bug where zooming in Library module can show a different preview in terms of color and saturation depending on the zoom ratio. Adobe is aware of this and working on the fix. Further, the only accurate way to view color and tone  is in Develop module, at 1:1 or greater. I do not believe the bug affects Develop. I can't see this issue on my end running Big Sur in either module but indeed, there are users who do see this in Library. A fix is coming.
