(evince:31227): Gdk-WARNING **: 10:59:29.833: Native Windows wider than 65535 pixels are not supported
(evince:31227): Gdk-CRITICAL **: 10:59:29.889: gdkdisplay-wayland.c:1402: Unable to create Cairo image surface: invalid value (typically too big) for the size of the input (surface, pattern, etc.)
