Could this be a problem with your installation of Qt4? I have been using the svg icons for a while now, without any issues. In what way are they displayed incorrectly? Did you compile qt4 without svg support? > (2) I still experience slow performance of pan/zoom feature with the > latest PyQt release (the last release for which I had no problem is the > 4.3.3 release). You'll find attached a simple test script: with PyQt > 4.3.3 pan/zoom is real-time, and with PyQt 4.4.3 it's really slower (in > fact, zooming and panning are happening at the right speed but after a > short delay from the mouse click) I think I need a more quantitative test script that proves this is an issue with mpl before I can be of help. On my machine, panning and zooming is just as fast with your test script as it is with a simple test plot in pylab using either the qt4agg or gtkagg backends. I have qt-4.4.1 and PyQt4-4.4.2 installed. Is there anyway you can profile the poor performance you are seeing?
