We currently have a bug in i965 related to modifiers. If the driver imports a tiled bo with a pitch >= 2^15 bytes, the driver will "retile" it to linear during miptree creation. I'll be sending out a fix for this soon. As far as I'm aware, there isn't a framework that can be used to test this issue. We should have a test to prevent a similar issue from occuring again.
Miptree retiling seems to have broken screenshotting with 8k+ displays: https://patchwork.freedesktop.org/patch/229507/
Nanley, is this fixed by? commit 0288fe8d0417730bdd5b3477130dd1dc32bdbcd3 Author: Nanley Chery <nanley.g.chery@intel.com> Date: Wed May 30 16:32:07 2018 -0700 i965/miptree: Use the correct BLT pitch Retile miptrees to a linear tiling less often. Retiling can cause issues with imported BOs.

(In reply to Andrés Gómez García from comment #2) > Nanley, is this fixed by? [...] My bad, I just realized that the report is about a missing piglit test. In that case, shouldn't we move this report to the "piglit" product?
