I have some graphic bug in rhino 6, in last service release as same as in last service release candidate.
Lines, like grid, curves or edges are everywhere “1.1x wider than normal”, so they not appear correctly thin as they should.
The normal wireframe rendering i’m used to is that every cuve is just 1 pixel wide (with AA off), here in RH6 i have almost every curve displayed somehow “dirty”.
Also i’ve found the “Focal blur” menu is blurred! … how ironic XD
See attached .gif to understand.
If I active GPU tessellation the problem is somehow more evident, or the same.
Vendor Name: ATI Technologies Inc.

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 .
At every update i hope it’s fixed, working with AA on make everything blurred, feels like… “imprecision” everywhere. And even AA can’t hide the problem, actually it make it randomly worse for orthogonal lines:
I was focused on purely vertical and horizontal lines as those need to get special cased to land exactly on pixel centers to look their best. I’ll check out the other cases that you mention in your most recent post.
Probably this “rendering” is a completely different stuff from a low level openGL rendering… it’s insanely heavy for just a curve…
This is just to see how i think it should be the final appearance (like in rhino 5).
Tried (6.8.18219.371, 07/08/2018) on 2 different machines: to me the problem is still there.
AA=off, straight lines have inconsistent width. An so all the other curves (grid lines too).
(testWireThicknessScale=1 but also any other value doesn’t help)
Did you refer to this release or another incoming?
