Created attachment 91399 [details] Screen shot of corruption, desktop effects enabled After upgrading intel driver from 2.99.906 to 2.99.907, I see corruption in certain cases, under KDE4.12: 1. With desktop effects enabled, right click on window title bar, popup menu looks like it has transparent background in places 2. With desktop effects disabled, window title bar has black rectangles, and right clicking on title bar, the popup menu has black background in places. I did a git bisect, and commit c79cb18407273dc7798618390bd0b7d69b0f80d6 seems to be responsible. Reverting this commit on 2.99.907 release restores the expected behaviour.
