yeah, but `std140` rules. The compiler would add two bytes as padding either way

is passing the whole ivec4 at once more performance than 4 ints individually ?

The padding thing. It's pain in the ass. So I use `vec4`, `ivec4` and `mat4`/`mat3` everywhere in UBO, and try to manually pack the data like in that screenshot with `Pad2` you posted.
This way I can stop worrying about compiler suddenly adding a padding, which is annoying to debug
