I experienced the same issue. Alt+End doesn't help! What do I do?

@herf Ok I will try again soon with the newest version I can find on this site. And yes, looks like cnmss is unrelated. Apologies. (http://www.techsupportforum.com/forums/f10/does-anyone-know-what-cnmss-is-resolved-154635.html) I will update after I reinstall the new version of the app. Thank you.

@shantanubdas311 said in F.lux auto disables when playing full screen games?: @TwoCables OK. I'm sorry, I really didn't mean it. I'm sorry too, but I had to be sure it was clear how it came across to me. But rest assured, it's all good and we're alright.

I use this LED screen as my extended monitor and I have flux installed. sometimes when I turn off flux to edit a photo with photoshop, even though the color I've set is white, when I have saved the image, it doesn't come out fully white in the screen. Does it have something to do with flux or the settings of the screen?

Same here on Z1 Compact 5.1.1 Lollipop. If I wait long enough and mess around with locking/unlocking the phone, the black screen goes away and I can use my phone again. Other than that (and the known issue when f.lux gets disabled for a second when an app is installing/updating) it's been working great!
