            Bug ID: 150303
           Summary: Accessing default web context before gtk_init results
                    in drawing failure (Gtk-WARNING **: drawing failure
                    for widget 'WebKitWebView': invalid value for an input
                    Visual*)

            Status: NEW

On WebKit2GTK+ version 2.10.2, drawing failures occur when (in this order):

1. webkit_web_context_get_default() gets called
2. gtk_init() gets called
3. a window with a WebKitWebView gets shown

In this order, however, no errors occur:

1. gtk_init() gets called
2. webkit_web_context_get_default() gets called
3. a window with a WebKitWebView gets shown

I have attached a minimal example showing this behavior. When running this, the following warnings are printed from time to time:
Gtk-WARNING **: drawing failure for widget 'WebKitWebView': invalid value for an input Visual*

This behavior only started to appear recently, my guess would be from version 2.10.1 onward.
