I've found a regression in latest Mesa from git. I'm getting a rendering distortions in Google Chrome with option "GPU compositing on all pages" enabled.

I did a git bisect. The first bad commit is:
523b611646ae15aa05ed37597ae9162de7290faf (linker: Use gl_shader_program::AttributeBindings for attrib locations)

Reproducible: always
