I am using an NVIDIA Quadro 4000 with NVIDIA driver 384.59 and running fs2_open 3.8.0 on x64 FreeBSD 11.1, compiled with SDL2 2.0.7, lua 5.1.5, openal-soft 1.18.2
fs2 runs just fine however there is a persistent "tear" during gameplay in the top 1/3rd of the screen. It's like a fixed line that is most apparent while moving about from the regular viewpoint. No other graphical anomalies are present that I can tell. The display looks good otherwise, and perfect if you're not moving around. The "tear" is maybe only a few pixels "thick" and most visible when moving vertically. Everything above and below this distorted line/tear looks great.
Has anyone ever experienced anything like this? Any ideas what would be causing it?
