Description Aleksander Morgado 2013-05-08 10:01:06 UTC 
Steps to reproduce:
 * Access a windows machine through RDP and run gtk-demo.
 * Install Microsoft's "Process Explorer" program, and run it.
 * Select the gtk-demo process and click "Properties", it will list a lot of info, include the "GDI handles"
 * Now, just move the mouse pointer over the gtk-demo window all the time, passing over clickable things and such.
 * The number of GDI handles goes up all the time.

Whenever the number of GDI handles reaches 10000, the GTK+ application will crash badly, as the handles retrieved by GetDC() and such will be invalid, making e.g. CreateDIBSection() fail, which in turn makes gdk_pixmap_new() fail, and which inner GTK+ doesn't really expect (see e.g bug 543209, bug 562574, or the more recent bug 699236).
