From ARB_shader_image_load_store spec:
" (0) How does this extension differ from the similar
EXT_shader_image_load_store?
RESOLVED: The functionality provided by this extension is very similar
to that provided by EXT_shader_image_load_stores. There are some
functional differences.
* "size" layout qualifiers replaced with "format" qualifiers.
* Image loads aren't restricted to "1x8", "1x16", "1x32", "2x32", and
"4x32" formats. Instead, each supported image format has a layout
qualifier, and values loaded from images are converted to an
vec4/ivec4/uvec4 representation appropriate for the image format."
size4x32 was valid for EXT_shader_image_load_store. That explains
why this test works properly on proprietary NVIDIA drivers, as
both extensions are supported.
Fixes freedesktop bug #93336
