Hello everyone,
I work with Inkscape nearly every day, but am now experiencing some painfully slow performance with some files (that I cannot share right now, sorry!) I'm working with Inkscape 0.91 r13725 on Ubuntu 15.10 with an i7-5500 and 16GB of RAM.
The designs are not particularly complex, but have one feature that might be relevant: I'm working with dimension accurate objects that can be very small, 0.1mm and below (I design printed circuit boards). The slowness becomes painful when zoomed in onto the small objects; it happens when I try zooming, choosing objects, moving them, and even changing tools from 'node' to 'select'. nearly every such operation I get the greyed-out Ubuntu stall. Working on the design when zoomed out is not practical, but it is quite a bit faster performing.
Another thing that's happening that could be related is the following prompts keep appearing on the console:
(inkscape:15569): Pango-CRITICAL **: pango_font_family_list_faces: assertion 'PANGO_IS_FONT_FAMILY (family)' failed
(inkscape:15569): Gtk-CRITICAL **: IA__gtk_tree_view_scroll_to_cell: assertion 'tree_view->priv->tree != NULL' failed
I could not find any report for how to handle these, and discover if they are related to the performance problems.
Searching for a solution through looking at bug reports, I've tried:
* Running with fresh preferences.xml * Geometric bounding box * Reducing the complexity of the design * Hiding layers (there are 24 layers) to only ones that are relevant for the operation (usually only two layers) * Hiding rulers and scroll-bars * Maximising memory and threads (with restart)
I'm out of ideas, and I hope that someone might be able to recommend something. If there are no ideas, I'll work on a design that I can share so that we could work though it.
Thanks, Saar.
