Inkscape developers,
I'm using a custom Windows x64 Inkscape build and I'm getting huge lags (1/2 second or more) when drawing with my Wacom Intuos 5. Rather than submit a bug report and waiting, I want to debug and fix it, if possible, myself.
Can someone give me a clue how to approach this? I was thinking of recording time stamps for input events in the event handler functions (e.g. sp_dyna_draw_context_root_handler() ) but if the input event handler isn't the bottleneck, I could measure time stamps of when the strokes show up on the screen, but in which function would I find that? Also, I don't think the processor is a bottleneck because I looked at the CPU usage when rapidly scribbling and it only uses 1/2 the throughput of 1 core.
Also, is anyone out there interested in Inkscape for Windows x64? I know the extra memory available doesn't help much, but believe that there should be a speed boost from the extra 8 registers and SSE2. If there is demand, are there any build issues that I can help with? I think I read from previous posts that the main work was to switch to MingW64. I'm currently cross compiling Inkscape on a Linux host.
