Oh hey cool, so this was an unauthorized update on my computer, and it's incredibly buggy. It stops working for any little reason, including things like opening a file inside Chrome. wtf. I'm goin to have to try and find the previous version, this one is super bad. The interfacing is also not intuitive, either.

@herf It looks like it was a GPU update, I went through and updated it and it is no longer having the issue.

It seems like NVIDIA pushed a bad driver.

People report that 387.92 fixes it.

Ok that's nice, thank you for your reply, I will try it as soon as I can!

I just have to tell you this is super nice. Thank you so much!

Now it's only choppy when the f.lux window is closed. Inch by inch, f.lux keeps getting better and better. I don't care about anything negative that some people might say about it, this is the best version so far.

The new version shows a list of all disabled programs, so it is easier to re-enable them. Hopefully updating soon for you, or you can download again from the website.

This seems only to happen for certain apps - so we made "fullscreen disable" also return the cursor to normal as a start.

I can look at it again, but it seemed too extreme to turn the cursor white for every fullscreen app, when it only affects some.

@herf

Hello thank you very much for the reply. I've expanded the color range and rebooted and the problem is currently gone and I am able to enjoy F.lux once again.

Yes it is a tricky thing to explain, and it is hard to explain "what's going on right now" vs. "what's going on through the day". People have a daily "compression" and "expansion" in their clock, and yet the main thing we haven't explained that the ideal case is when they cancel out and help you sleep when you need to.

If you shut off all the lights at noon, your clock would "advance" from the day before - as if you had traveled east. And if you kept all the lights off until noon, you'd "delay" due to seeing brighter light later in the day.

Normally these two regions cancel each other out, so ultimately we have to talk about the whole daily exposure.

Most of the heuristic advice ("see more light in the morning and less at night") is because most people with sleep trouble are "delayed" or late types. But this advice is not for everyone - many older people wake up earlier than they'd like, so they may need different advice.

You might notice that we focus mostly on "sensitivity" in the graph, and we're trying to hint at the overall daily response. But there are still some things missing, because it's complicated & hard to explain.
