No, although I do have a few fonts and a couple extra in ~/.fonts, but the application opens straight away. The image does not have fonts in it and it opens reasonably fast. As soon the user zooms in or pan around the image then the slow rendering starts. I have now looked a bit more into this problem and it seems that inkscape is slower in MSWindows (dual boot machine). So I concluded that this is an inkscape issue, rather than Gentoo specific. Also, googling around it seems that zooming in a lot (more than 1000%) or using many filters (as this user is on the particular image) slows down inkscape: http://www.inkscapeforum.com/viewtopic.php?f=5&t=8721 As suggested in the thread above, a work around until the inkscape code is improved is to change the View mode to 'No Filters'. This trick restores rendering speed to reasonable levels. -- Regards, Mick
