UPDATE: So, after hours of trying different things I found that this "slowness" bug is caused when the images are set to sizes that are not native. For example, say you have a 1000x1000 image, but set the size to 100x100 (letting the browser to the scaling) --- THEN the scroll is slow. Now, this may or may not be related to GWT directly, but I'd still appreciate any advice. Is this something others have observed? Any way to get around it?
