It keeps the same pivot center. Would you like to test on the stable kicad if you experience the same behavior? Consider that in the stable kicad, the pivot center is fixed on the board center.
The "trackball" is fixed to your screen, so whatever is the transformations of the board, the "trackball" is always in your fullscreen. So when you rotate, you should consider the full screen as your "trackball" and not the "pivot center" With this new pivot center thing.. what I found for me was that it makes less confusion if I always center the pivot (mouse center or spacebar) in order to "pan" the board. So this way the pivot center is centered with the "trackball" on the screen center.

This could be the reason for the "weird" behavior, because you will suddenly get a lever arm from the center of the window and to the board local point. This will make the pcb move a lot compared to how much the cursor moves. Is this an artifact of a "beta" implementation of the space select point on the pcb or is that a design decision? _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
