What do you have for a graphics adapter? Intel, AMD, or NVIDIA? I'm thinking there's some setting in the graphic adapter's control panel that you have to toggle. Another possible culprit could be Windows. Go into the f.lux settings and turn on "Always use Windows internal color table".

Please add a CheckBox I beg you, in HDR mode the pink/red tint is horrible and looks so bad

Solar time is different from standard time. I could try to explain it, but I recommend doing an internet search for "what is solar time?" It's an interesting subject. Edit: Also, here's Michael Herf's answer when I asked what solar time is: https://forum.justgetflux.com/topic/7526/what-is-solar-time It's also explained here: https://justgetflux.com/news/pages/v4/readme/ It says this: Solar Time? Solar Time is the time a clock would say if it were based on the sun. If our clocks worked like this, noon would happen when the sun was directly overhead. We now show Solar Time in f.lux interface, because we think it’s important. If your solar time is after the current clock time, it’s likely that you live in a place that’s easy for night owls to be (because they can wake up late). And if you’re in a place where the solar time is much earlier than what your clock says, it’s easier for early birds, because they can go to bed early.

@herf Oh that's amazing thank you so much, that worked perfectly! Thanks again for the help. :)

Oh, I see. Thanks :)

@herf Ah right. Windows apps are kept around pretty differently. I see why this decision was made. Regardless, I think people would still benefit from being able to add an EXE name. Under the right click menu item to disable for a specific time or application, would it be possible to add a button to the list that just says "For an exe..." which would open a file picker when clicked on? Adding a program through this method would add an exception for the full path of the executable instead of the window title. The main window title functionality would stay put and this would just be something used by people who want to add the EXE manually because they know what they're doing.

4.119 - still huge usage. But just got new pc and on this build [pc] f.lux not using much cpu, not at all. Guess it just not optimized for old hardware.

It looks to me like it's due to your color settings for your display adapter. I'm referring to whatever software is installed for that, whether it's for Intel onboard video, AMD onboard video, or an NVIDIA or AMD GPU which would be either NVIDIA Control Panel or AMD Radeon Software.

Can you take a photo of what you're seeing? To post it, click the Upload Image button that's on the far-right (it's a vertical rectangle-shaped button with the top-right corner dog-eared).

@Pierre-Le-Fier said in Windows Event 5858 WMI-activity with 4.119: Select * from WmiMonitorBrightness Yes this is us trying to get access to the current monitor brightness, which does sometimes work in Windows 7. I don't think a failure here is unexpected, but the log is certainly annoying.

Came here about this issue as well as dimming being disabled when opening settings and every time the settings window is switched to the display "tab." This setting fixes the notifications (which oddly only seem to be bright the first time they're opened in a while, but closing and reopening the bar reactivates the dimming) AND the settings window issue, so that's great. As for you reasoning for not enabling the option by default, I highly doubt leaving it broken is going to encourage MS to fix their crappy OS. There are still numerous minor bugs that have existed for years. And they don't even care about security issues (often ignore ones reported to them until the discoverer of the flaw goes public) and serious bugs, so something minor like this will likely not be fixed for years, if ever, and that's assuming they're even aware of it. Plus, they have their own version of this (Night Light), so that makes it even less likely they'll bother fixing something that's an issue for f.lux. It's just not worth bothering users in the misguided hope that it will lead to MS fixing things. Also, off-topic, but I'll mention it here instead of making a new post just for it: The text in the main window that says "The sun has set. Light is making your body later." doesn't make any sense and has always bugged me. I've just always assumed whoever wrote it is ESL or used a translator for it and that it's trying to say something like "The sun has set, light will delay your sleep cycle" or "The sun has set, light will disrupt your circadian rhythm."

tellah, I'm not sure if it helps, but I'm getting a similar issue. Things are not dimming for me at all. I can tap it, or jiggle a different level of brightness with the mouse, but the screen stays the same. There's no dimming. In desperation the workaround is to use the task manager to kill F.lux and then open it manually again. I use the shortcut to reopen. But it works straight away. It's a bit of a pest to have to do this. For the last month or so f.lux didn't change the screen until I clicked on it or changed any setting. Sometimes I just needed to put the f.lux window at the top. It was as if it was asleep and I had to waken it. Now it's worse. I miss my self activiting f.lux

Hi Ellie - mainly I would look at your wake time in the program and make sure it's set properly. Also, the location can affect this as well, but I assume you've set that up...

Turning that option on seems to just disable any coloring at all, game or not.

I'm getting this as well, though on the Mac (version 40.1 on a 2018 MBP with Radeon and Intel graphics).
