Maurice Amsellem updated FLEX-34107:
------------------------------------
Comment: was deleted
(was: After debugging for hours, my conclusions are the following:
- all coordinates and computations are fine,
- renderers are displayed shifted by 5 pixels upward on *low* densities from
their computed coordinates. You can check that by selecting the row, you will
see that the selection rect is higher than it should be.
- the separators disappear because the next renderer background masks the
separator (because of the shift).
Attached screenshot showing the 5 pixel shift (top separator in red, bottom
separator in blue, gap=0)
Since the coordinates are OK, then it must be the transform matrix.
I checked the transform.concatenatedMatrix or a renderer on high and low
density:
high density: a=1 b=0 c=0 d=1 (this is the identity matrix)
low density: a=5 b=0 c=0 d=5 => scaled matrix.
Note sure yet how this works, but my intuition is that the matrix is the reason
for the error.
Thanks for catching that.
