OK, you do have several plugins I haven't seen before, and one that's been known to cause trouble in the past. As a first step, I would try temporarily disabling all plugins other than SilverLining (that's us) and Gizmo (which we need) via the plugin admin menu, and see if things render properly then. If so, start adding plugins back in until you find the culprit.
If that doesn't work, there are some specific combinations of anti-aliasing and HDR settings that have problems on AMD cards. Try changing your AA setting in X-Plane's graphics settings and/or the graphics quality and see if that clears it up.
Afraid it will take a little bit of experimentation, but there are lots of components here that can interact in strange ways. If you narrow it down, please let us know what you find here as it may help others.
