Comment= # 5 on bug 97305<= /a> from Marek Ol=C5=A1=C3=A1k 
Pre-GCN cards require an alignment of 256 bytes for uniform bu=
ffers. GCN cards
only require 4 byte alignment there.

All other buffer binding points require 1, 2, or 4 bytes depending on the t=
exel
size. It's really min(texel_size, 4).

Whatever the closed OpenGL driver reports doesn't correspond to the reality.

The limits reported by our Vulkan driver are very similar to Mesa.
