JTextPane and images in html

I have a problem with rendering of images in a JTextPane rendering of images.

Only parts of the images are rendered (like 50x50 pixels). When i move the mouse inside the pane everything renders correctly.

Am I doing something wrong? Or is this a known problem? (From different posts on the Internet I understand that JTextPane has problems)
