I can't see how this could be anything other than an XFree bug.
During animation, lines are drawn with the sequence:
XGrabServer(dpy);
XInstallColormap(dpy, ...)
XDrawLines(dpy, Scr.root, ...);
XFlush(dpy);
XDrawLines(dpy, Scr.root, ...);
XUngrabServer(dpy);
The second XDrawLines should erase the first.
The Grab should ensure that nothing else happens to the display
during the draws. The gc for XDrawLines is setup for xor'ing.
The only time I've seen line dropping is using Exceed, where Exceed
doesn't have total control of the display.
