Description

I have a "show flat buttons" tasklist option on.

Occasionally, one or more buttons in the tasklist switches to a non-flat state and it stays that way until I go to panel properties and switch the option off and on.

I haven't figured what causes this error, it happens rarely. It seems related to switching windows or some of them raising themselves.

Xfce 4.10, RHEL5, custom-compiled gtk stack.

I've seen this error on Ubuntu as well but I haven't noticed it for a while now.
