The "blue shadows" as shown in this screenshot
https://bugs.freedesktop.org/show_bug.cgi?id=100531#c2 have been fixed for me
with the latest update in the padoka ppa.

What remains are the "fancy coloured textures" on my R9 290 (Hawaii, CGN 1.1)
which were also reported on R9 270 (Curacao/Pitcairn, CGN 1.0) in unigine
