Comment 1

[Jonathan Kew [:jfkthame]]

The differences here seem to be minor issues with antialiasing pixels at the top and bottom -- probably timing-dependent, according to exactly how invalidation and repainting works out. The actual feature being tested is unaffected. I think we should just annotate this as fuzzy, and move on.
