I use 184.108.40.20627 (307027) Public (CE Build ce-43.0.4829)
From March or April, all my records containing scanned business cards look like empty in the preview/quick edit window (). If I double click the record and open it in a separate window, everything looks fine, and I can see and edit the record. The small image of the card in the list looks fine as well. But I usually edit my records in the right window without opening it in a separate window, so the bug is a big problem for me.
A month ago support answered that they are aware of the bug, but nothing seems changed.
