Hello !

View → Layout → Three Columns

INBOX contains a message with PDF attachment

Clicking on PDF icon on rightmost vertical MIME picker-bar,
brakes the layout: 
1. Scrollbars are missing, 
2. PDF document is only partly visible, 
3. Vertical MIME picker-bar in gone.
4. Restarting Claws Mail restores the layout.
