                    Still Responds To Clicks
    Classification: Unclassified

We are using webkit2gtk for our LightDM Greeter. After the update to webkit2gtk 2.10.0 and gtk 3.18 the greeter renders a blank white screen. Because the greeter runs as a child process of LightDM outside of a DE, I am not sure how to debug it with gdb. The log for the greeter contains the following errors, which repeat infinitely until the greeter is killed:


(lightdm-webkit2-greeter:30686): Gtk-WARNING **: drawing failure for widget 'WebKitWebView': invalid value for an input Visual*

(lightdm-webkit2-greeter:30686): Gtk-WARNING **: drawing failure for widget 'GtkWindow': invalid value for an input Visual*

(lightdm-webkit2-greeter:30686): Gtk-WARNING **: drawing failure for widget 'WebKitWebView': invalid value for an input Visual*

(lightdm-webkit2-greeter:30686): Gtk-WARNING **: drawing failure for widget 'GtkWindow': invalid value for an input Visual*


I have searched extensively for any information related to this error but couldn't find anything that was even remotely relevant. Any advise/assistance in identifying and fixing the problem will be greatly appreciated. Thanks!
