Description FreeDesktop Bugzilla Database Corruption Fix User 2005-05-20 10:23:16 UTC 
XGetImage and XGetSubImage, when called on the Composite backing pixmap of a
manually redirected top-level window, fail when part of the requested image data
corresponds to parts of the window that lie outside the root window.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

This was a misunderstanding on my part about how Composite worked.  The redirected windows are clipped by the root window.  Marking invalid.
