Some cairo-dock icons disappear after waking up ubuntu from suspense mode

[barthus]

Hi all.

I love cairo-dock, its a dock and everything works well. However, there is one little issue: When I wake up my laptop from suspend mode the 'folder'* icons have changed: They are somewhat transparent with some noise. When the mouse is over the icon, the icons suddenly look normal. As soon as the mouse leaves the icons, the latter become again transparent. Well, it doesn't annoy me much but may be there is some fix.

Any idea?

* Folder icons: Well, I moved some folders from the nautilus onto the cairo-dock such that they appear in the dock. Some important folders are faster accessible now.

Nobody has an idea?

Thanks for any help, cheers!
