Sometimes, holding item in hands and then eating someting completely breaks the UI. Two items end up in hands at the same time, one is zoomed in and has cyan background and covers a large portion of the upper left corner (50% horizontally and 30% vertically). No other item can be held, and hands can not be emptied, and hands are renamed to one of the items. Hands look empty (or sometimes partially filled with one or other of the items) but when right clicking the empty hands the other (already used up) item shows up.
In this particular case you can see the large Makarov in the upper left corner, half of the Makarov in the hands, and the header saying "CANNED TUNA" instead of HANDS.
After exiting the server, the Makarov is still in the upper left corner inside a big cyan colored area.
