<pre>No because it's not a bug.
Per the Vulkan spec "26.11.3. Depth Bias":
"depthBiasSlopeFactor scales the maximum depth slope of the polygon, and
depthBiasConstantFactor scales an implementation-dependent constant that
relates to the usable resolution of the depth buffer."
and,
"The minimum resolvable difference r is an implementation-dependent parameter
that depends on the depth buffer representation."
That means, it might render differently based on that implementation-dependent
parameter. Note that it likely renders something different with NVIDIA as well.
Closing as we can't do anything.
Thanks for the report!</pre>
