visual rendering resolution not quite right

[jonorthwash]

Something appears to be off with the resolution of the visual tree rendering. Based on the type of "blurry" that it is, my guess is that it's being rendered at a low resolution initially and then is being oversampled when the bitmap is created for display.

This isn't a major issue—the visual representation is still quite usable—but aside from the minor aesthetic annoyance, it means the visual representation is being displayed at a larger size than it has to be, which could interact negatively with #2.
