It's been stated before (where? TBD) that when a channel is using roScreen and a screensaver is supposed to kick in, instead a black (blank) screen is shown for the screen saving duration.
Today in somewhat circuitous way i noticed this is not the case for a "classic" model (2xxx). So i wonder, what is more specifically the relation between roScreen and system screen-saver not being invoked? Like,
Is it that firmware version specific (fw3 vs fw5+)?
Or is it a question of hardware capabilities (e.g. OpenGLES vs DirectFB-only models)?
