--- Comment #2 from Kai <kai at dev.carbon-project.org> --- Created attachment 90433 --> https://bugs.freedesktop.org/attachment.cgi?id=90433&action=edit dmesg output for DRM/radeon I'm seeing this too with a PITCAIRN chip (stack detailed below). Though the tearing (one, 27" monitor with 2560x1440, KDE 4.11, composited) appears like five ccentimeters from the top whenever there is fast movement or quick image changes. I'm not seeing this with Catalyst. (Sorry for not reporting this earlier, but I totally forgot to.) No error/warning (except not finding some cyrillic font) is logged to Xorg.0.log ? do you still want to have it?
