Yes we have been investigating this fir some weeks now, unfortunately seems to be a regression in the hardware graphics driver that is not going to be fixed in this cycle. My best guess is that pygame double buffering is no longer supported by the driver and your observing a vsync related frame redraw that should be happening in the hidden buffer. The blank band will grow as the scene gets more complicated :( Other pygame activities will also be affected (I've seen one mention of someone seeing something similar in Maze).

I've looked to see if there's anything I can do to improve Physics at the activity level, but haven't found any options yet.

> Chart Activity: Opened a very big file from measure - it kept on going forever. I cannot find a way to tell it to stop reading the file. I tried to stop the activity but it looks like it will not stop until it finishes reading. After a bit the menus at the top of the screen were no longer visible (as if it was trying to stop) but I can see the data field and the chart field, which is still bringing in and displaying/plotting the data

It seems that the gain slider is a position control, not a gain control as in audio mode, this doesn’t seem to be explained in the documentation on wiki.sl.o. The position control can be used to position zero on the screen.
