Logs & Dumps

Info regarding the draw:
draw: 1227
shuffle: 1
shuffle_same: 0
real16src: 0
process_ba: 2
process_rg: 1
shuffle_across: 1
write_rg: 0

Seems that the written alpha is wrong on the draw:
Left VK, right GL:

01227_vertex.txt
01227_context.txt

Disabling texture barriers or lowering blending to Minimum also gets around the issue so it's something related to barriers.
