The implication is that the SVG file is being re-rendered when the
buttons are pressed - yet the buttons are different widgets entirely,
positioned above the SVG file.

Surely it's unnecessary for the SVG file to be re-rendered just because
an unrelated button is used? The complexity of the rest of the GUI
shouldn't matter in the situation described by the original poster.
