Unfortunately the patch does not quite do as I hoped. Debug below shows the problem:

The problem is that after calling Release on the top level interface it calls dfb_layer_context_activate This is what ends up clearing the FB (via activing Window manager etc). It then destroys this context and carries on shutting down. I will see if I can tweak the patch meanwhile any help is appreciated many thanks Daniel -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel J Laird Sent: 2008 Oct 15 09:22 To: Denis Oliver Kropp Cc: directfb-dev@directfb.org Subject: Re: [directfb-dev] Layer Clearing at shutdown in DFB 1.2.x Yep, that's what I was in the middle of implementing.
