--- Comment #6 from tarpoon@gmx.de --- (In reply to Gregor Münch from comment #5)
Some people reported this should actually got fixed by 0fb5a505fac7be0a1831b565019f0f04369e56bd, but looks like it isnt for all. https://bugs.freedesktop.org/show_bug.cgi?id=100531
Will test myself in some days...
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 (valley/heaven) https://bugs.freedesktop.org/show_bug.cgi?id=100593#c4
