Image clearly showing a red/blue swap
The driver appears to swap the red and blue channels of
VK_FORMAT_A1R5G5B5_UNORM_PACK16 textures. As can be seen in the game Tales of
Eternia in my emulator PPSSPP:
<a href="https://user-images.githubusercontent.com/1274014/34218237-f0c1981a-e5ad-11e7-9b76-683a344c52fc.png">https://user-images.githubusercontent.com/1274014/34218237-f0c1981a-e5ad-11e7-9b76-683a344c52fc.png</a>
The game uses RGBA8888 textures for the background and ARGB1555 textures for
the characters. They look a bit blue and ill, which is obviously an R/B channel
swap. The colors are correct with the same code on other Vulkan
implementations, so this points strongly to A1R5G5B5 being defined wrong in the
driver.</pre>
