I have a uniform buffer bound to binding 0 that is row_major that works correctly, but if I bind a second one it ignores the row_major qualifier and also if I set the default globally as row_major.
So it ignores the row_major in: layout(binding = 1, std140, row_major) uniform ModelBuffer
In fact I managed to get it to 'work' by wrapping a matrix read from the buffer in a dummy function like so:
Which magically makes it respect the row_major layout
