Is this a regression? If so what is the last working version of mesa for you?
Comment 4 Hai 2018-12-27 01:10:53 UTC 
It's not an regression. I tried Mesa 18.2.2, it also failed, thanks.

Any idea of this issue? Thanks.
Comment 7 Bas Nieuwenhuizen 2019-01-02 15:02:12 UTC 
Hmm, I can actually reproduce (thought we would not be able to since we have a pretty much 100% pass-rate on the 1.1.3 mustpass list on a bunch of HW).

However I also noticed that it is not on the mustpass list?
Comment 8 Bas Nieuwenhuizen 2019-01-02 17:05:30 UTC 
This should fix it:

Verified with this patch. This test case can pass with this patch, thanks.
