I have narrowed a bit the bug:
here is a small testcase which very often freezes, but only when in
Xinerama mode and when using a truetype font:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <X11/Xlib.h>
int main(int argc, char **argv)
{
int i;
GC gc;
XGCValues gcv;
Display *dpy = XOpenDisplay(NULL);
int blackColor = BlackPixel(dpy, DefaultScreen(dpy));
int whiteColor = WhitePixel(dpy, DefaultScreen(dpy));
Window w = XCreateSimpleWindow(dpy, DefaultRootWindow(dpy), 0, 0, 200, 500, 0,
blackColor, blackColor);
XSelectInput(dpy, w, StructureNotifyMask);
XMapWindow(dpy, w);
gcv.font = XLoadFont(dpy,
"-misc-yikatu-medium-r-normal-*-*-280-*-*-p-*-iso10646-1");
gc = XCreateGC(dpy, w, GCFont, &gcv);
XSetForeground(dpy, gc, whiteColor);
for(;;)
{
XEvent e;
XNextEvent(dpy, &e);
if (e.type == MapNotify)
break;
}
for(i = 0; i < 50; i++)
XDrawString(dpy, w, gc, i, i * 10, " Y a r g l a a !", 16);
XSync(dpy, False);
sleep(1);
return 0;
}
I dunno how to always synchronize operations, so I did an XSync() at the
end and it freezes there. You can retrieve the font here:
ftp://awak.dyndns.org/yikatu.ttf (it's 26k big)
I'm using X4.1.0 from debian/sid
What can I do more to help debug this (very annoying) problem ?
