Wireframe geometry crashes ARM Windows Computers

On a Windows computer with an ARM chip (Snapdragon)

Run the box or sphere command to create geometry in a wireframe view
As soon as the command completes Rhino crashes.
This is a GPU driver crash. We need to detect Rhino running on this specific GPU and have wire drawing performed with a different set of instructions.

Grasshopper: Long processing times on change of Model Block Visibility > Content Cache

Tested in 8.12.24240.02001

Issue: When pushing visibility changes via content cache for 250 blocks there is an unexpected lag of 3 1/2 to 4 minutes to complete.

To repeat:

open users 3dm file and grasshopper file that are privately attached in a zip file.

change the 4 boolean inputs and Push Content.

Rebuild: not clear when preview is automatic

Looking at the code the preview is automatic when the total point count is below 500. But the preview button is always clickable, and it is not clear for the user when they should click Preview or if they are waiting for the automatic preview to finish.

Maybe it could be optimized that the preview button is enabled/disabled depending on if the previews are automatic, or by allowing the user to toggle automatic previews themselves.

NestedClippingDrawing: All option now creates clipping section drawings ordered by section names in alphabetical order

When I select the clipping planes manually (1)(2), the first section is created at the lower-left location. I was expecting it to be at the upper-left location. Maybe an option like FirstSEC=UpperLeft/LowerLeft is needed.

When the All option is used (3), the sections are created in a random order in this example. I think it makes sense to order the sections by names, and in https://docs.mcneel.com/rhino/8/help/en-us/index.htm#commands/layer.htm#NaturalSortOrder like the layer list does.

Grasshopper: Added Texture Evaluator component for rasterizing a procedural texture

Information about material name and density enriches the exported STEP242 files.

If your NX design contains PMI dimensions defined with a single-limit tolerance, the capability lets you preserve the manufacturing intent in STEP files for downstream MBD, machining, and drawing workflows.

DXF/DWG translator
This enhancement lets you import large drawing files faster than earlier NX versions.

DXF/DWG and 2D Exchange translators
If your NX design contains PMI dimensions defined with a single-limit tolerance, the capability lets you preserve the manufacturing intent in DXF/DWG files for downstream MBD, machining, and drawing workflows.

Grasshopper: Extrusion object to mesh

Steps taken:
In Grasshopper, create a rectangle in XY and extrude it in Z
Connect both a Simple Mesh and a Mesh Brep component to the output of the Extrude component
Observed bugs:
-> The Simple Mesh component creates a 1-faced mesh
-> The Mesh Brep component creates a mesh with 18 faces
Expected behavior:
In Rhino 7, both components create the expected 4-face mesh:

Grasshopper: Curve Seam Location on Offset Regression

Summary: The file provided works as expected in Rh7 and reportedly in 8.4 as well. In 8.5.24072.13001 the error was reported and confirmed in 8.6.

To Repeat:

Open attached grasshopper file in Rhino 7
Open same file in Rhino 8.5 or above
Note: a similar issue (unresolved) is on youtrack from 7 years ago
