michael campbell (3di) added a comment to T68920: Reduce shadow terminator artifacts.

@Laurent Noel (c2ba), I think someone should try an automatic solution before we add manual settings.
The issue happens when a reflection ray goes into the mesh, and then wrong shadow comes from when it exits. So if we ignore that exit, it may solve the most common type of problem. It's even possible to experiment with this using just a shader setup with a transparent BSDF on the backside, to see how well it works. Either way, any solution will need changes to the BSDF evaluation first.

Chris Malcheski (CMalcheski) added a comment to T70242: CUDA invalid value error when using 2.15GB texture.

Smaller worked. This was an obvious pointer overflow within Cuda. The texture size crossed the limit of positive values for a 31-bit float (bits 0-30 being the value; bit 31 being the sign bit). With bit 31 set, pointers were being treated as negative numbers. Why are they using 32-bit ANYTHING with today's cards? Oh well. Now it's known that limit exists. This is why I hate high level languages.

Marcus Brock (atomedia) added a comment to T69535: CPU + GPU render precision differences for small, far away area light.

I want to add that this is not just an error that appears in very few situations. It appears (for my understanding) for nearly every realistic sized light (lights <1m).
I have a big project where I can render no single frame without this error. ~90% of the light comes from area lights (10x10cm floor lights).
It looks like the contrast or brightness setting is different when rendering with CPU or GPU. GPU frames are always a lot brighter than CPU frames. I currently don't know which device produces the correct output. It's annoying and very time consuming that you cannot use both devices at the same time anymore to speed up rendering.

You have to apply the patch and compile Blender to test the feature, it is not in the daily builds. Also your file does not have velocity information (the array size is 0). So without the patch and without custom velocities, Cycles is just using an interpolation between the previous, current, and next frames.

I have some blurriness, but it doesn't seem to look right. (see Images)
This is a particle system that I exported and then reimported to reverse the movement. And the plane is a dupliobject on the vertices of the ABC.
I would not expect to see a clear outline of the plane in the image with motion blur. Also, the position of the blur is set to Center. But this seems more like Start. And the shutter duration also has no effect.

To address this issue, what do you think about adding a "shadow bias" parameter to control an offset from the surface along the geometric normal ? I know its not a perfect solution but at least it would allow users to avoid a lot of rendering artifacts that are due to shadow termination.

Not so fast. Distance along surface normal to edge as implemented here is a different operation than distance to edge in D5743 and cannot be replicated by the features added in that patch. The reason to do distance along surface normal is that you get consistent derivatives along the surface, the original devtalk past linked at the top shows an illustration of how distance along surface normal (left) approximately compares to distance to nearest edge (right).
