@Tylerr the "disable for app" feature will disable f.lux completely, and the "disable fullscreen" feature should affect only one screen (at least on most multiple monitor setups - love to hear what yours is if this isn't true).
We have thought about applying the per-screen behavior to "disable for app" and might add it, but it only "makes sense" in the fullscreen case, where the content might have its own color toning (like movies or games). Usually people don't want white pages that are one color on one screen and a different color on a second screen.
Yeah, this is due to the way Windows is. We users have to force Windows to render the mouse cursor differently. Here are 3 different options to choose from:
Use the Beta version of f.lux for Windows. It has an option that I think is enabled by default called "Software mouse cursor when needed (fixes "white cursor")"
Open the Windows Magnifier and set it to 100% (and leave it open).
Enable pointer trails via the Registry in such a way where the trails aren't visible but it still makes Windows render it in software which makes it affected by f.lux.
Of course, the best option is using the Beta version of f.lux for Windows. If you wish to instead enable pointer trails via the Registry, then let me know and I'll show you how to do it. I'll save myself the time and effort of writing up the instructions now because I'd much rather see you enjoy using the Beta version of f.lux. It's the best option for more reasons than just this!
We are hearing about a washed-out color profile from LG that is causing this issue. We aren't really sure why they're doing this, but removing the profile (details below) has fixed other people with this issue.
Post again somewhere (new thread, reply to a thread, etc.) if you have any questions about the Beta version after you begin using it. I'll be happy to help if I'm able to! I'll see that you posted thanks to the way that this forum works.
Some games overrride f.lux, some do not. For those that override it, try borderless windowed mode. If that's not an option or if the game still overrides f.lux in borderless windowed mode, then you'll have to use Windowed mode. If that's not an option or if it doesn't work again, then you'll have to reduce your monitor's brightness. If you are playing in total darkness (no room lights or anything), then I would say that's your problem.
