-----------------------+-------------------------
If you have a vector drawn in the map window the first time you change the
mode from "2D View" to "Vector digitizer" it clears the map window and in
the console I see an exception:
{{{

.
GException
:
Rendering failed: Expecting 825x586 image but got 825x622
image.
}}}
One workaround after the exception is to click on the "Render Map" icon.
I suspect the problem is that the switch to "Vector digitizer" mode adds a
row of toolbar icons reducing the area to draw the image but the size
change has not propogated to everything that needs it. Interestingly
switching modes back to "2D View" and then to "Vector digitizer" a second
time does not produce the error even though the vector digitizer toolbar
disappears and then is re-added.
