Created attachment 134041<= /a> [details] Screenshot comparison When trying to display=20 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 texture= s. My card is AMD Radeon HD 7870.
Please attach the corresponding glxinfo output. FWIW, not seeing the problem on Kaveri with recent Git master.

Added glxinfo attachment. Also upgraded to Mesa 17.2, but the problem still exists, glxinfo log is fr= om new version.
Maybe an SI-specific bug? Looks like the bottom part of the sc= reenshot comparison for me on both Carrizo and Tonga (VI) with Git master.

Test program
The bug is still present for me with mesa 18.3.4-1
I wrote a little test program which compares an uploaded
3dtexture mipmap with the corresponding output of glGetTexImage.
It should output nothing, but on my desktop pc it outputs:
Error in level 2
Error in level 3
Error in level 4
Compile with "gcc test.c -o test -lglfw -lepoxy"
