In case BitBlt() fails with ERROR_INVALID_HANDLE, the most probable cause
2005-10-01 Tor Lillqvist <email@example.com> * gdk/win32/gdkdrawable-win32.c (blit_from_pixmap): In case BitBlt() fails with ERROR_INVALID_HANDLE, the most probable cause is that the the desktop isn't visible because the session has been switched, the screen is locked, or a terminal server session disconnected, so no error message necessary. (#137796) It is of course remotely possible that BitBlt() failing with ERROR_INVALID_HANDLE might also be caused by some other problem. We could strive for perfection and track whether the desktop is visible by using WTSRegisterSessionNotification() and handling WM_WTSESSION_CHANGE. I think that's overdoing it just for this issue, though. If we would track desktop visibility, we should then avoid even trying to update the display at all while the desktop isn't visible.
