Since
https://gitorious.org/mypaint/mypaint/commit/95225b99e0937828ae87c0df22fbafd6962e7615
, MyPaint is performing excessively large redraws of the entire document when
painting, not just the extent of the last few dabs. The effect is visible when
"Visualize Rendering" is turned on: see the attached files.
Related bug: these redraws are now happening in response to pointer motion
events with a pressure of zero (mouse, hovering with a Wacom tablet). The
effect is visible as a fickering of the document bbox area when "Visualize
Rendering" is turned on.
Both problems were introduced at the same time:
