Has anyone ever tried to invalidate a portion of the screen successfully without seeing flickering?
I have a portion of the screen (on a SurfaceView) which changes rarely and I don't want to draw this portion if possible because it saves ~16% of all drawing code. So I keep a flag whether I should lock the entire canvas (if this part of the screen is dirty) or a part of it (if it's not). Well, *something* surely happens, but not what I'd expect: 1. The non-dirty part of the screen starts flickering as I stop drawing it. 2. Visually (i.e. I can't prove it by taking a screenshot via Eclipse's DDMS plugin - everything looks fine), it appears that 2 frames are drawn continuously one on top of the other - the current one, and the previous. I appreciate *any* hints, even "don't do it, it doesn't work", so I can concentrate on something more meaningful.
