Thank you for the quick reply! You are right. I fixed the input and now it is
evident that the difference is in the windowMatrix:
Code:
WindowMatrix
3.4.0:
[0] {960.00000000000000, 0.00000000000000000, 0.00000000000000000,
0.00000000000000000}
[1] {0.00000000000000000, 443.00000000000000, 0.00000000000000000,
0.00000000000000000}
[2] {0.00000000000000000, 0.00000000000000000, 0.50000000000000000,
0.00000000000000000}
[3] {960.00000000000000, 581.00000000000000, 0.50000000000000000,
1.0000000000000000}
3.2.1
[0] {960.00000000000000, 0.00000000000000000, 0.00000000000000000,
0.00000000000000000}
[1] {0.00000000000000000, 443.00000000000000, 0.00000000000000000,
0.00000000000000000}
[2] {0.00000000000000000, 0.00000000000000000, 0.50000000000000000,
0.00000000000000000}
[3] {960.00000000000000, 443.00000000000000, 0.50000000000000000,
1.0000000000000000}
Is seems like the difference in value [3][1] is what gives the vertical offset
on the screen of 138 pixels (between the cursor and the object I normally
display on the cursor position).
Do you have any suggestion of how I could solve this?
