Useful uses for a compositor #1
Some videos this time, they’re not particularly good quality but that doesn’t matter. First – http://folks.o-hand.com/iain/watch-updates.ogg
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 – http://folks.o-hand.com/iain/totem-button.ogg
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.
