Useful uses for a compositor #1

Some videos this time, they’re not particularly good quality but that doesn’t matter. First –

Its like acid, but cheaper!

So what exactly are we seeing?

Well, everytime a section of the screen needs to be redrawn, the compositor draws it correctly, and then picks a random colour and overlays that colour on the region that was redrawn. So you can watch screen updates as they happen. Just by watching the colours change.

Besides being a cheap night in, what use is it?

Well, here is video #2 –

Again, crap quality, but down in the bottom left corner of the screen, we can see that something is constantly redrawing itself. That something is the totem-mozilla play button. It seems to be constantly redrawing itself for no apparent reason. Bastien got a bug for you.

    The button is actually glowing, rather than just constantly redrawing itself the same – not sure if that’s a feature or a bug…

    I like this new compositor; I wish there was only some fade effects for menus :)
