Setting the fallback to resolution 300,300 for either postscript or PDF back-ends appears to change the matrix used for normal line draw, but not for text rendering. The problem does not occur unless alpha blending is used (forcing the fallback) Using a fallback resolution of 72,72 renders the line draw at the correct locations.
