It's probably exactly that. It's under View Extended and called "Toggle tracking fire weapon". This will immediately switch to Ctrl + F6 view when you shoot something and with that switched on, you can even use it to follow your gun rounds with the F6 views can't do. Pretty sick feature for videos if you ask me and it's been there since Lock On at least, but it's everything else than widely known. Check the info bar in outside views to see if it's on ATM, shown by a "+" just preceding the F# label there.
 
It "fixes itself" by simply loading another mission as such things reset on every load if you didn't know how to switch it and accidently turned it on.
 

Thanks for your comments. It actually was the 3Dmigoto mod not working properly for me, I use it to reduce the haze intensity to 0.4 since the Mustang shader isn't working anymyore. Well, that and my crappy eyes (need some more post-cataract-surgery laser shots into my left eye actually). Hadn't been flying any other modules after the Apache release, so I thought it was just it. With the mod, I can see things much better, and it also has some options that Reshade would supply, I may even try playing around with those. Also, switching the monocle off made it a bit better, but I'd prefer to have the immersion of it being visible.

I took off with NWS off as well. I switch it off as soon as the speed indicator comes to life, just by experience with other DCS modules. And mostly I paddle after touchdown, but I "forgot" to do that once or twice already, without getting any issues though.
 
But: There are two ways to control yaw more precise on landing that can also be used:
 
1 Toe brakes
2 reverse aileron
 
As for the latter one: stick to the left: yaw right and the other way round. This happens because you decrease the area of airbrake on the side that you're pointing your stick away from. Good old trick, works very well.
