As you can see in the .png it is not antialiasing because its not grey-scale pixels, those are completely black(0,0,0).
Antialiasing is disabled in both RH5 and RH6, as I want it to be.
( I can’t work properly with AA on, I’ll lose a lot of useful details. In fact i think AA for cad is just dumb… but more generally, AA is a smoothing that fakes the shapes, i prefer to see original clean and sharp shapes. )
In RH5 wireframe mode render curves/edges/grid flawlessly with AA off.
EDIT: i didn’t explain well what happen in the .gif. Other than that “dirty” curves rendering, the axes and the grid line at 0 (horizontal to view) change it thickness ±1 pixel, its not an error of the .gif, sometimes it really go 2x (the axys) or disappear (the grid).
EDIT 2: also the “Make 2D” form/window have all elements blurred out as the “Focus Blur” shown in the .gif .
EDIT 3: also the selection window
The problem is only for horizontal lines. It’s like the pixel are not rendered 1:1 but something like 1:1.001 .
RH5 is fine in this matter too.
Edit 4: it happens in both, horizontal and vertical lines (just horizontal for the selection window tough).
Here i’m just zooming out:
Orthogonal lines should never be 2pixel wide…
(I tried and, even with AA on the effect is washed away somehow, but still visible)
The fastest way to see if the problem i’m having occur is to see if a circle is “clean” or not.
Sorry for the spam, I hope it helps.
