[Mesa-dev] vulkan: regression on Haswell

[Jacek Konieczny]

Hi,

I have been playing with Vulkan API and using the Mesa Intel Vulkan
driver from the 'vulkan' branch.

Recent driver upgrade has broken my, previously working code, causing
massive flickering and graphical artifacts.

git bisect have shown, that this is the breaking change:

commit 7ebbc3946ae9cffb3c3db522dcbe2f1041633164 (refs/bisect/bad)
Author: Nanley Chery <nanley.g.chery at intel.com>
Date:   Fri Mar 4 11:43:19 2016 -0800

    anv/meta: Minimize height of images used for copies

It might be, that my code is broken, but it worked correctly before this
change and has been checked with validation layers and Valgrind.
