Im here with another issue. Im not sure if I installed something from AUR that caused this, but now my ODT thumbnails went from normal thumbnails, to now being black squares. I reset all my cinnamon panel settings, restarted cinnamon and cleared the thumbnail cache. But for some reason, my odt thumbnails still come up black. They used to not do this, but any time I edit an odt file, it now resorts to this. I don't know what caused this to begin. Would anyone know what causes this?
