EDIT: Finally was able to duplicate it! It seems to be preset specific though which is interesting. More in a bit.
Okay this took a couple hours to narrow down and still not clear what the issue is - but at least I can duplicate it now on a clean save with no mods or DLC installed. It seems preset specific as I could not duplicate this on some presets. The GS Azura preset, however, it happens consistently.
Here is a zip file:
https://drive.google.com/open?id=0B9Amn ... VNGYTAycUU It has the complete Azura preset with the binary, enblocal, enbseries.ini, and all the shaders being used. It uses weathers but I tested with weathers enabled and with weathers disabled (and no enbhelper.dll installed) and the artifact was still there. I tried changing the SSS settings to what I had in another preset that did not have the problem but it made no difference. I enabled/disabled all effects one at a time and only SSS being disabled fixed the issue. I changed the text alpha flag from true to false and neither made a difference.
Also in the ZIP is a clean save with no mods or dlc - just skyrim and update files. I did have SKSE installed. It is saved in the Bannered Mare in Whiterun behind the bar with Helga. The save is of my test character looking at a book behind the counter which has the issue.
I will note I only disabled all the plugins. Since my mod install is large and complex I did not want to uninstall everything - so just disabled the plugins so the save would not have them in it. But my texture packs and files were all installed.
