French) Organization: Massachusetts Institute of Technology Lines: 13 I've noticed (in a rather painful manner) that the pixmap handling code in Xqdss is amazingly slow. For example, creating a 1000x1000x8 pixmap and then filling it with WhitePixel using XFillRectangle takes over 2 minutes! (This is quite worthless, considering I was hoping to do double-buffering). Does anyone know why this is so, and if so how to fix it? All rendering routines appear to be this slow. (like 15 seconds to draw a small 4-sided polygon).
