Dear Murpholino,

the slow shifting might be related to your graphics card (sorry if this has already been mentioned, I didn't read the entire thread).

#> cat ~/.coot-preferences/coot.scm
(set-use-stroke-characters 1)

I guess that ccp4 coot set's this in their start-up script. In case you use your own coot and do not set this, the shifting can get very slow with some graphics cards, in case an atom label is displayed.

Best,
Tim

@PE: I mean graphically and I guess computationally.

    It's generally the same, but CCP4 applies a few patches to the coot
    source, uses different compiler and compilation options, different
    versions of dependencies (as you've seen coot depends on a huge number
    of third-party libraries), etc.

    You may try building coot in the same way as it is build by CCP4:

    first install bzr and then:

    bzr checkout bzr+http://oisin.rc-harwell.ac.uk/bzr/series-70/trunk
    <http://oisin.rc-harwell.ac.uk/bzr/series-70/trunk> devtools
    cd devtools
    export FLAGS="-O3 -fno-strict-aliasing -pipe -mtune=core2"
    export LDFLAGS="-s -Wl,--build-id=sha1"
    ./cj build coot
    misc/linux-rpath.sh ./install
