           Summary: eglglessink: fix expose after changing the
                    window_handle
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: ylatuya at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When the window handle changes (eg:a device rotation)
and no buffer is processed before doing an expose, the last
texture is no longer valid in the current context, so the last
buffer needs to be uploaded again.
