i am using the most recent Zotero version (5.0.94) on MacOS 11.2 - and I am having the same problem. When I move my Zotero window from one screen to another screen with a different resolution, the Zotero UI is only a quarter of the actual window. The same behavior occurs on multiple computers of colleagues.
(Please start new threads for new issues — the thread you posted to was last updated in 2016 and referred to a fix in a much older version of Zotero. I've moved this to a new thread.)

No, you're not. This was a bug under Big Sur that was fixed in Zotero 5.0.95 several weeks ago. You just need to update to that.
