hi list!
the pd-gui is very slow on ubuntu 14.04. and any version of pd that i have tested (043..046). it looks like this is caused by pd (tcltk) redrawing the complete window contents instead of only the part that has changed. it is especially slow when the window copntains (visual) arrays.
selecting everything in edit-mode, and moving it around caused a similar behaviour under 12.04 and iir ealier. (not very surprising though, that moving everything around causes everything to be redrawn...), but now this happens all the time, even when just a slider is moved. (or a single object in edit-mode)
is there anything that i could do about this, other than avoiding (avoiding to redraw) any sliders etc. (and keeping the gui as minimal as possible)? like installing an older (or newer) tcltk version, or changing a script? does that happen on other distributions/os too?
bis denn! martin
meanwhile i have found out a little more about this problem (which affects others too, i have found a few similar reports) it is caused by the graphic-cards driver, which apparently does not (yet) support some 2d acceleration which is needed for quick screen-redraw in pd and tcltk.

use the fglrx driver instead of radeon. or another gpu...
