Jeeze, I need to learn how to use gmail, folks. Sorry for sending emails directly to people on this list instead of to the list itself. Alright, I built the entire <a href="http://X.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> X.org</a> system from git (which was somewhat painful, but not altogether terrible) and the problem seems to have gone away. I'm not sure why I was getting the regressions with the Gentoo provided X-servers. I should note that I was able to the build the X server from git before but I still had these problems. It's only now that I've built the very latest version along with all the other junk that the problem has gone away. <div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div> <div> On 4/19/07, James Cloos <<a href="mailto:cloos+pdx-xorg@jhcloos.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">cloos+pdx-xorg@jhcloos.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> >>>>> "Joel" == Joel Feiner <<a href="mailto:jafeiner@gmail.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">jafeiner@gmail.com</a>> writes: Joel> I have an ATi x300 (r300 driver).

This happens for me (on Radeon M7, r100 driver) as well, even w/o the composite module loaded. I use icewm. Switching to a desktop with a seamonkey or firefox window is especially slow. Desktops with emacs or urxvt windows are more tolerable, but not nearly as fast as things used to be. (One significant difference between the likes of emacs or urxvt vs zilla is xft vs cairo.) My xserver, ati driver, xcb, libx11, cairo, mesa are all git master, I use EXA, and cairo may or may not be using glitz. (I can't tell; glitz is linked in, but I can't be sure whether the glitz, xcb or libx11 backends are in use....) This has been the case for a while. -JimC -- James Cloos <<a href="mailto:cloos@jhcloos.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> cloos@jhcloos.com</a>> OpenPGP: 1024D/ED7DAEA6 </blockquote></div> </div></blockquote></div>
