Description genetita 2012-12-20 19:23:39 UTC
I've prepared a simple application that receive clicks from the mouse on a window, store the clicked point and draws lines from all the stored points to all the rest of points, like a N graph.

It works fine for the first 10, 20 points but when you reach a certain number of points the render gets floods on certain areas. 
Resize the window sometimes fixes the problem sometimes not.

It happens in Ubuntu Linux 12.04 64 bits and Mac OSX 10.7.5

Libraries used:
gtk+-2.0, version 2.24.11
cairo, version 1.12.2
