accelerated rotation uses textures to rotate the desktop, so the max size would be 2048x2048. > > Also, for anyone else in this conversation, I don't belong to the list. > > > > > The problem that I encountered, however, was of painfully slow > > > > performance, even for ordinary 2D operations, like moving a > > > > window.

It's not that hard to install from git so long as you have the needed build dependencies installed (xorg, xserver-dev packages from your distro).
