That was the first thing I tried when I had the Problem, but the Update had no impact. I searched for new drivers today, but they are up to date. The manual also was not helpfull for me, but the error dosen't seem to be a comon problem and as you sad very Hardware configuration dependent.

@Sebastian Schneider (Redphoenix) @Marko Tatalovic (Fuxna) The OSL node took me about a minute to bake on an i5-3570k (4.4 GHz, 4 threads total) using the settings I listed above in that blend file. The most important thing is to set the render sample to 1 in the render properties tab. Setting it higher slows the bake down drastically, but it's unneeded. I still think unlocking the bevel samples in the default bevel shader would be a good experiment and I think the OSL node is a good workaround for now.

The cause of problems so dependent on the setup is very difficult to investigate.
Have you tried upgrading GPU drivers?

Fynn G (TheFynn) added a comment to T74178: OpenCL mantaflow smoke rendering hanging/crashes.

thats strange, its even the same architecture(Polaris).
I've tested a lot today and it dosen't happen with Tile sizes of 64 and lower, extremly low sample count or volume without simulation data. Also Raw cache worked, but not VDB or Uni cache. RAM and VRAM are both utilized lower than 50%. (combining CPU and GPU or disabeling Noise had no impact).

Marko Tatalovic (Fuxna) added a comment to T72011: Visible wireframe artifacts after baking normal map with bevel shader (2).

15 - 30 min for baking bevel is not a right solution. Question is why are normal of the non beveled edges affected in the first place. Can't they be masked and mixed with original normals? All we got on this ticket are distractions, and no response from devs at all. Is it a bug, do we don't understand how to use it, is it a known limitation bla bla bla...

@Nominous (Nominous) Maybe, but for me computation time was insane.

The duplicate by Max (Raytraced) that was merged to this report forgot to mention that he experimented with increasing the bevel shader samples past 16 (512+) by using a custom OSL node, which seems to solve wireframe artifacts in the normal map bake: https://polycount.com/discussion/comment/2701351/#Comment_2701351 Maybe that would be a good path toward solving this problem?

Tautvydas Andrikys (esminis) added a comment to T70697: Cycles denoising on CPU buffer overflow.

I could reproduce it reliably, now I have not checked again, but from code I still see that there is no changes to mitigate this in at least kernel_filter_nlm_update_output method.

Charlie Jolly (charlie) added a comment to T74198: Rounding error in ColorRamp node.

Color Ramps are converted to a texture and then sampled from a 256 px wide image. There is an optimisation in Eevee when there are only two stops which explains why it breaks after adding another stop.

We still don't know if the problem is with an NVidia driver or if it's in blender. Let's wait and see what the Cycles team will say.

We are using gcc7 for official builds to comply with LTS distros and OpenVFX platform. Does not mean we do not support more recent compilers (most devs actually use gcc 8 or 9 already I think).

Jeroen Bakker (jbakker) added a comment to T74119: Preview render in Cycles becomes yellow tinted when cursor is on the file browser.

Issue is that the gpu_shader_image_color_frag is being used. And the file browser sets the color parameter of that shader to render the icons.
The draw manager should reset the color parameter to fix this issue.
