I think the thing that brings your performance down is transparency.
Editing markers and measuring rubber bands both use transparency (and
GRASS edits don't).
FPWIPF uses QPixmap to render (and is rendered on
the X-server). If FPWIPF is disabled, QImage is used which afaik is
pure software rendering.
So should it be faster or slower with with FPWIPF enabled?
Currently, with FPWIPF *enabled*, during digitizing rendering is 66
times worse, whereas outside digitising it is 2-3 times better. This
seems inconsistent.
Doesn't anybody really know why FPWIPF enabled slows down performance in
digitizing mode but improves it once diigitizing is quit?
If QT version matters, I'm using 4.3.4.
