Previously config.thread_level was lowered to 1 as a 'fix', but I believe this was mistaken for the config.method setting directly below it. (Unless the multithreading caused issues with the update)
Later config.method was also lowered to 0 after performance issues were noticed, but config.thread_level was untouched.
I believe increasing config.thread_level back to 6 should restore multithreaded saving of screenshots, and reduce save times proportionally with resolution.
