Comment 17 for bug 99508

I had this in Feisty and now in Gutsy. It's also when using beryl instead of compiz. I think it's rather a heliodor bug because when using emerald (in Feisty) the artefacts didn't appear. I'm using nvidia-glx-new now, it was the same with nvidia-glx under Feisty. All buttons still work, but sometimes it happens that the whole decoration turns grey. My artefacts look the same as the screenshots above. I don't think (but I'm not sure) that the error occured with windows that weren't maximized. The buttons in the decoration also all still work because when I hover the buttons, all artefacts in the decorations disappear.
