Description Martin Peres 2018-07-12 10:37:21 UTC 
The test spec@glsl-1.30@execution@tex-miplevel-selection texture() cubearrayshadow failed once on our skl-6260u machine.

Failure:
Expected level: 4
Observed: shadow comparison failed
Fetch level: 3, baselevel: 2, maxlevel: 5, minlod: 2, maxlod: 3, bias: -2, mipfilter: yes
Summary: 48509/48510 passed

This seems like it is pretty rare, but I filed the bug anyway to keep track of it in cibuglog.

Feel free to close it if you are not interested

I've tested tex-miplevel-selection on mesa 18.1.3 and mesa-git(e2aa6ba732) with i5-6440HQ and all tests passed:
Summary: 58212/58212 passed

Is this failure still reproducible? If yes then what exact command was used to run test?

No, the reproduction rate is probably close to 1/1000 :s

This is the sort of failures that is just so annoying to deal with... but we always end up hitting!

Closing, after one year without any reproduction :o
