There seem to be an absolutely huge delay in loading the NEWT canvas on linux (Kubuntu). Any sketch with P2D or or P3D, takes forever to load on Kubuntu (64bit), whilst Java2D sketches run OK. The actual performance once loaded for say esfera sketch seems OK. However the issue is even worse on ArchLinux with Fluxbox or XFCE desktops as the canvas fails to load (a frame displays but is greyed out), so no P3D or P2D sketches run. Processing-2.0b8 works fine on all above systems. OK I've done a bit more experimenting, and curiously I seem to be getting better results launching sketches via the command line, well actually from jEdit (can't do with all that typing), except I need to 'hide' the jEdit frame to get the sketch frame to render sketches, so it seems there may some sort of "windowing issue". I actually came to this from updating ruby-processing, and I'm now beginning to doubt whether the sketches actually ran at all from the processing-ide (I tried re-running sketches from Kubuntu and no P2D, P3D sketches ran.
