--- Comment #15 from Timothy Arceri t_arceri@yahoo.com.au --- Created attachment 142313 --> https://bugs.freedesktop.org/attachment.cgi?id=142313&action=edit Hack around issue
I've found the source of the problem. It seems that the tgsi indirect indexing optimisation is causing issues on Vega for some reason. I've attached a hack which disables it resulting in correct rendering.
