Userscripts.org

I've got a problem with this feature. Somehow it does not work anymore.
Some weeks ago it did work fine, but actually nothing happens when i hover the pictures.

Ah. I just tried some things.
The problem are some styles from stylish.

I have no idea why it does not work with this style activated because it's just css and should not change the script.

Ah. Just solved the problem on my own.
The style does remove the round corners, which i haven't noticed yet.
Then i turned the "Show rounded profile pictures." option off and it does work again.
