--- Comment #10 from CraZy bisCuiT psycheldic_kingdom@freenet.de --- This problem affects me as well on mesa 17.04 and llvm 4.0.0-1 with AMD RX 480. Any ideas what causes this problem?
We can't expect a patch from the developer since the studio doesn't exist anymore. For some reason proprietary AMD and nVidia drivers do work.
