Good, this is what I expected. > > Maybe you just need a full display update after disabling the gl > > scanout? > Do you still think updating full display is needed? It certainly isn't required, gtk wouldn't access the dma-buf any more after scanout_disable(). Without display update the last guest display may remain visible until the guest reloads the driver though. With display update the gtk ui should show the (blank) DisplaySurface instead. So it is more cosmetical. cheers, Gerd
