It's just not worth paying attention to those idiots. Is there a bug in (what's likely to be) their OpenGL texture renderer? Yeah. Does it really make any difference? Eh. I suppose there are some people out there to whom it's relevant. Certainly not I. I would far rather Google spend their time on other things than fix this.

I find it laughable that they claim that only fanboys would be interested in whether other applications can display images in full color (despite the fact that this would seem to disprove their notion that the hardware is incapable of doing so) and then also fawn over the (apparently huge) difference between 16-bit and 18-bit color. Which is more fanboyish: pointing out that if you're unhappy with the rendering in one application that you can use another one, available for free on the Android Market, or obsessing about a 1-bit-per-subpixel difference?
