Bug ID: 102581
Summary: 3D texture mipmapping broken
Product: Mesa
Version: 17.1
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi

Screenshot comparison
When trying to display
https://www.shadertoy.com/view/4llcR4
i get artifacts near horizon due to mipmapping (artifacts are absent with
mipmapping disabled).
It works as expected with the proprietary driver (under Windows) on the same
machine.
See attached image for Screenshot comparison.
So either mipmap generation or display seems to be erroneous for 3D textures.
My card is AMD Radeon HD 7870.
