But then after the page has fully loaded, it somehow fades to an almost invisible state. I have uploaded a picture which displays this effect. In the indicated red square a chapter image is loaded, but is almost not visible. I am not completely sure if I had this effect on earlier firmware versions as well.
But does anyone know if this is a known bug? And if there is a solution for it?

I've seen quite a few chapter images that are light and others that are dark. It seems to depend on the contrast of the original image and how well they convert to a 16 level display. Remember that the H2O's display is limited to 16 levels of grey (actually, 14 plus white and black) which is not great for displaying an image that was created using 256 or more levels.
If you have access to edit the book, you can extract the images and modify them in your favourite image editor -- I like using GIMP with the 16 grey level palette ( GraysSixteen.zip ) to convert the images so I get a better idea of what they will look like on my ereader's screen and then played with contrast etc. Other occasions, I've simply posterized the image to increase the contrast.
