Suddenly, some terrible banding sets in everywhere.
Quake 2 textures are no longer smooth, they are still filtered (or with their strange filtering that sometimes shows some serious blockiness) but now show some banding specially on the dark and far areas where textures have the slightest gradients.
Videos show equivalent banding, being specially worse with cartoons where mpeg4 blocks pop in and pop out on solid colours like sitting ducks.
And all over the xfce desktop some slight banding has set on every little gradient, on the background, the shutdown menu, the launchbar...
This didn't used to happen, I don't remember if xfce banding was there or not, but Quake 2 or video banding wasn't definitely there. It happened when I was on a trip.
At first I've just dissed it as firmware corruption, I've been using the hotfix 2. Since the device isn't the most stable one ever, it crashes from time to time, and maybe something got corrupted in the way, and in the middle of nowhere there where little I could do. But now that I had reflashed and installed hotfix 3 it no longer should be the case.
I've tried setting Xorg to use 24 or 32 bit depth instead of 16 bit but both failed to start.
An other SD card I've used for developing where I installed the firmware also displays similar symptoms.
I know what 16 bit colours can do, I had a Voodoo 3 (whose accelerated modes where limited to 16 bits) and games still looked just as good, but this looks like a downscale to 8 bit.
I don't have anything particularly important on the nand so I can reflash if it is needed.
Thanks for the help, and I hope it isn't anything physical.
EDIT: Oh, I've forgot, I have a good camera with a good macro so I can post photos if needed, but banding looked a lot like this
I remembered that project from when I played Bioshock on my trusty Radeon 9600 Pro and had the same problem, though in that case, it was expected.
EDIT 2: I've remembered this topic http://www.gp32x.de/board/index.php?/topic/54882-are-we-stuck-at-16bit-graphics/page__p__884528__hl__banding__fromsearch__1&#entry884528 and I see smooth bands with notaz's op_gammatool.
