Not all monitors included in screenshot if stacked vertically.

Created attachment 174355 [details] Small program demonstrating the issue (source) I use GTK+ to take screenshots in my program. It works great; however, someone has just reported that if their monitors are stacked vertically, the monitors in the top row aren't included in the screenshot properly (it looks garbled). I was able to confirm this; I opened up my graphics driver's control panel, positioned my secondary monitor on top of the main one in the configuration, took a screenshot using my program, and while the main monitor (positioned on the bottom) shows up fine in the screenshot, the secondary monitor (positioned above the main monitor) shows up garbled. Attached is an example program. To reproduce, obviously you'll need more than one monitor, and you'll need to configure your system so that one of those monitors is stacked vertically on top of the other one. I'm not sure if this is a bug with my program (is there more than one window besides the root window?) or with GTK/GDK. Any help would be appreciated.
