There were three screens next to each other, I unplugged the right-most one. I now realize that I can reliably reproduce this by placing a maximized window (like KMail) on that screen. Once unplugged, the KMail window (the actual window with content) is moved one screen left, to the one that is now the right-most one, while KMail window decorations are moved all the way to the left-most screen. > Are you using the OpenGL or XRender compositor > (just asking as the xrender could still be wrong as I didn't adjust it)?
