Is it right place to file such bug, or is there better?) Let me go into a few details, what do I mean by "performance decreased"/"slow performance", I hope it might help. Slow performance with <<Option "AccellDFS" "off">> in xorg.conf, but with proper rendering. Slow performance means, everything "freezes", making like 1fps or maybe even 0.5fps (1 frame per 1-3 seconds) when : * moving window * scrolling contents of windows (no metter kde,gnome - WM is KDE) * using some apps like: ** typing in OpenOffice ** typing in firefox ** etc. While, some features perform well, like: * watching video * 3d opengl stuff * virtual machine in virtualbox * most console apps (most of my work) But when one of those runs in parrarell with one of those from first group, like for example: * watching video and typing/scrooling/window-moving in OO/firefox Than everything "freezes" and goes into "1 frame per 1-3 seconds". Connection is that, those activities, which involves "freezing mode"/"1 frame per 1-3 second" seems like similar or even the same, which makes "tearing" or problems with refeshing in normal performance mode <<Option "AccellDFS" "on">>.
