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. There was no problems with the older GTK2 Claws Mail version 3.x.x. Claws Mail version 4.1.0 GTK 3.24.33 / GLib 2.70.0 Locale: en_US.utf8 (charset: UTF-8) Operating System: Linux 5.16.8-arch1-1.0 (i686) Plugin - PDF Viewer This plugin enables the viewing of PDF and PostScript attachments using the Poppler 22.03.0 Lib and the gs tool.
Additional comment: The main problem is - once when application/pdf view breaks layout, the layout remains broken for all other following messages and mime views. Only restarting helps. Claws Mail version 4.2.0
