Monitor comes back from standby without f.lux colors [fixed in new beta]

 Thanks, 
 I have it failing now - turns out I had to turn off the login screen on wake, or it would hide the problem.

 Good, At first I thought it maybe one of settings, but tried all , on/off with same results. I login with admin, so i never see that screen (except for sec on boot)

 Apparently finding out that a monitor has slept is one of the unsolved problems in Windows. I made a workaround for this case here: https://justgetflux.com/flux-setup4-35.exe See if it works?

 Need more testing, but after reboot it seems so far to work (2 times so far pass).

 Yep, it's fixed! In both Tests, all good now. Thanks

 I updated to 4.35 and the issue was fixed only if my monitor turns off as a result of power option being triggered (ex: "turn off the display" after 1 minute idle). If the display turns off when I close and open my laptop lid, the issue remains, exactly like @disqQ 's description on test 1: On test 1 If I stay in the same window, the color stays as daylight. It is only back to normal (as set by the schedule) after I change to another window. Changing between tabs in a browser does not trigger f.lux to fix the color. The color is fixed at once, not slowly. Thanks. I am using Win10 Pro with Intel HD Graphics 4400.

 This has started happening to me since a recent Windows 10 update (I think). When my monitor switches back on after me being idle, f.lux is not working. I have to alt+page up/down to get it to activate again. I'm using f.lux 4.120.

 Can you post f.lux options > driver info?
