With today's typical amount of graphics cards memory we should probably
increase the default setting of that parameter to maybe 400 or 450.
With 2GB of GPU RAM I have found the sweet spot to be
opencl_memory_headroom=400
opencl_memory_requirement=768
Just had the issue again with

I exported several pictures and toggled nvidia-smi in another terminal
to see if GPU-Memory usage will increase => nothing the like.

[opencl] frequent opencl errors encountered; disabling opencl for this
session!
