Sorry for the delayed reaction, thank you for the patch which has been

Great, thanks!

In addition to git/gitlab and infrequently used mailinglist, the
developers do chat in the IRC channels #gegl and #gimp on GIMPnet -
also used by GNOME on


Note that the OpenCL code in GEGL works but multi-core CPU code most
often will be faster (in particular in GIMP with lower OpenCL coverage
of operations than in the GEGL provided set), thus the opencl / GPU
acceleration is most often best left off. I however think OpenCL still
is a good fit for GPU accelerating GEGL and hope for future
improvements to both GEGL operations and OpenCL platforms.

I noticed that, too. And it made me wonder, because on the same hardware
Darktable seems to work much faster when OpenCL is enabled than when it
is disabled. Any clues what's so different?
