Package: libcairo1
Version: 0.4.0-1
Severity: important
When cairo_show_surface id called with a surface created with
CAIRO_FORMAT_RGB24 pixel format, the app crash with xlib BadMatch error.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 211 error_code 8 request_code 72 minor_code 0)
(Note to programmers: normally, X errors are reported
asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
Test program :
#include <cairo/cairo.h>
#include <cairo/cairo-xlib.h>
#include <gtk/gtk.h>
#include <gdk/gdk.h>
void cairo_gdk (cairo_t* ct, GdkDrawable* window);
gint expose (GtkWidget* widget, GdkEventExpose* event);
GtkWidget *label;
cairo_surface_t *s;
int main(int argc, char **argv)
{
GtkWidget *win;
gtk_init (&argc, &argv);
win = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_set_size_request (win, 100, 100);
label = gtk_label_new ("sds");
gtk_container_add (win, label);
g_signal_connect (G_OBJECT (label), "expose-event", G_CALLBACK
