Sorry if this goes somewhere else. I searched the forums for a GIMP or Software questions thread and couldn't find anything. Anyway, whenever I open a animated gif in gimp it does this automatic optimization thing and removes the things that don't change in subsequent frames. This is great for reducing the file size but it makes editing the gif far more complicated. Is there anyway to disable this? Thanks,

What version of GIMP are you using? I just launched v2.8 here and opened a GIF, and it didn't do anything to the image. I did launch it under Linux, but in my experience it behaves the same under Windows. How big a file is the GIF you opened? It isn't something ridiculously huge, is it?

Gimp 2.8 in Windows. I've noticed it does this with a handful of gifs but not every single one.  The first frame is always perfect but the subsequent frames are missing data. I'm assuming that GIMP is removing data that doesn't change because it still animates perfectly.Examples:   Here's how one frame in the last one looks zoomed in.

I wonder if launching GIMP and then choosing "Open As Layers" to open the GIF might get around this behavior - it might be worth trying.

A quick search points to GIMP's differencing engine selecting the pixels which can be dropped, and I don't see an obvious toggle for this setting in the preferences. I'm not sure if using another application to open the image and change the color profile would make any difference, but might give it a shot. If the ones that keep the full background have one color profile and the problem ones another then that might be a jumping off point.
