Morrowind Graphics Extender - ugly SSAO shader artifacts

[cheesechoker]

I'm using Morrowind Overhaul & Morrowind Graphics Extender XE 0.9.10 (the latest version, I think). While playing, I see weird artifacts from the "SSAO HQ" shader that MGEXE provides. It gives a nasty dither/"glass tile" effect, mostly on distant objects near the view distance cutoff. I'm not using Distant Lands.

Obviously I can remove the SSAO shader, but I do like the look in areas of the frame where it's not hideous. Can it be fixed?
