In the latest Experimental Build, I have this disabled, and I still get the weird zooming in and out, it mostly zooms out, but occasionally zooms further in than my presets. I have generated a Report File and put it up on Pastebin, but im not sure if it'll contain any useful information. This might just be confirmation bias, but I think it happens more frequently when I move my scroll wheel (such as to dial in a new heading or speed). Reverting to a non-Experimental build (0.1.98 Alpha) seems to fix the issue for me, so I will continue using the non-Experimental for now. If you would like me to provide more information regarding my issue in the latest experimental build, let me know.
