[Bug 27919] Re: Switching workspace: redraw is slow

[Chris Wagner]

Ok, this is pretty interesting...

I tried out the Xubuntu Live CD, out of curiousity, and noticed that the "slow drawing" problem did not exist.  I checked the xorg.conf that was being used; it was using "nv".

So, I thought maybe the issue had been resolved.  I downloaded a daily build of the regular Ubuntu Live CD.    The problem still existed for plain-old Ubuntu.

Then, I switched back to the "nv" driver on my regular installation (I was using the proprietary "nvidia" because the problem did not exist with that).  The problem still existed.  So, I installed xubuntu/xfce packages on this installation, rebooted, and logged into an Xfce session => no slowness.  Log out, log into GNOME => slowness.

I certainly thought this problem was probably at the X level, but now I have no idea.  Perhaps it has to do with the window manager used by GNOME vs. Xfce?
