release. Some images would render as fully or partially black, others would render with bits of Firefox toolbar and even others would render with different portions of the web page and other X11 applications. Xorg log would show spammed "Render bad image" messages. Opera renders correctly, except it breaks malloc (e.g. mplayer will fail to allocate memory while Opera is running). I've kept ports up to date, and have even rebuilt all ports, but nothing fixes these problems. These problems continue to occur on even the latest 7-STABLE builds.
