--- Comment #2 from darkbasic darkbasic@linuxsystems.it --- Created attachment 94348 --> https://bugs.freedesktop.org/attachment.cgi?id=94348&action=edit dump
I noticed it suddently started working flawlessly so I asked myself what fixed it: patches from https://bugs.freedesktop.org/show_bug.cgi?id=72785 did fix it.
I currently apply: 0001-SelectionDAG-Factor-ISD-MUL-lowering-code-out-of-DAG.patch 0002-SelectionDAG-Use-helper-function-to-improve-legaliza.patch 0001-R600-SI-Custom-select-64-bit-ADD.patch
Beware that I modified "UP.Threshold = 500" to "UP.Threshold = 100" because "bfgminer --scrypt" didn't work otherwise.
I attached dump from R600_DEBUG=cs GEGL_USE_OPENCL=yes gimp without the patches.
