Black image with Haze Removal + OpenCL

Software darktable

I think that’s the amount of memory that can be allocated in one chunk; however, all memory can be allocated (in several chunks). For my 6 GB card:

0.067616 [opencl_init] device 0 `GeForce GTX 1060 6GB' supports image sizes of 16384 x 32768
0.067620 [opencl_init] device 0 `GeForce GTX 1060 6GB' allows GPU memory allocations of up to 1519MB
