The only differences on the two screenshots are the plot and the acc and vel values. I used the same machine config for both, I'll set up different ini files so the titlebar shows which build I'm using. I did git reset --hard 689e5cb185f87deba62391cd184f21f360ce2246, make clean, ./autogen.sh, ./configure --enable-run-in-place, make, sudo make setuid ... is this correct?
