f.lux causing memory leaks in other running applications?

I have a late 2013 model 21.5" iMac with 16GB ram running OS X 10.11.4. I was having this problem where most applications were allocating memory out of control and the OS would have allocated tens of GB in swap, highest I saw was 56GB (more info on Macrumors forum).
After reinstalling OSX and trying to figure out what the issue was I have now pinpointed f.lux (I was using the latest version installed through brew cask) to be the cause of the problem:
I disabled f.lux and rebooted, ran the computer for a few days without any memory problems. Then, yesterday morning, I ran f.lux again and left the computer alone. 9 hours later it had allocated 13GB in swap with various applications allocating the memory.
These are screenshots of Activity Monitor just after I started f.lux and then 9 hours later:

So, for now I have disabled f.lux. If there's some interest in figuring out why this happens I can provide additional system info or run other versions of f.lux.

f.lux updates the system profile many times per day on dual-GPU macs, and it's possible that Photoshop doesn't expect this to happen and leaks memory. Sounds like quite a bit.
