Show pointer position with Ctrl key draws a black rectangle
Last modified: 2011-02-24 05:58:09 UTC
When the "Show position of pointer when the Control key is pressed" option is activated, pressing Ctrl draws a black rectangle around the mouse pointer. I'm not sure which is the intended effect to be drawn, but this does not seem right.
Code lives in gnome-settings-daemon.
That code looks like it didn't get ported to GTK+ 3.x.
