Centering active glyph in preview panel G3

Something very weird is going on with the preview panel, with one line it jumps around randomly, two lines it gives up completely, many (20) lines it tries to center something, but still not the active glyph. Always center option is checked :confused:

What Glyphs version (the four digit number) do you have?

Sorry, 3198.

This is still a problem in 3200.
