The tooltip for items in the first 8 slots of the inventory show the incorrect label text. They appear to show the label for the item in the slot +10.
eg. Logbook in slot 8, showed as "Foliage" which was in slot 18.
If I resize the inventory window it temporarily resolves itself, but when moving items around it happens again.
Perhaps similar to T903, but I didn't fully understand that issue, and it was closed months ago.
FYI, I'm playing with v0.199.217 on OSX 10.10.5 through Steam using the native launcher.
