In the mournhold sewers, certain meshes seem to dissapear/not load, fade away before popping back in, not have any water despite being below water level, or having bright lighting in dark areas. This is really annoying and i don't know what could be causing it. The only mods that might have an impact are Patch for Purists, Morrowind Optimization Patch, Correct Meshes, and Project Atlas and the openmw log doesn't seem to have anything out of the ordinary so i don't know what could be causing this.

Does it change if you enable force shaders? I've seen a similar issue where someone was using Intel integrated graphics, and the driver was getting confused by fixed-function stuff.

Bisect shows that the issue is in the Animation::setAlpha() (presumably a data race during transparency update for creatures).
PR #2355 seems to fix this issue for me.

Force shaders was enabled when i made those screenshots, not sure if disabling will make a difference though

I've given it an LGTM, so as there are symptoms of it not being merged, I'm going to merge it if no one objects soon.

Check the latest nightly build - this issue should be fixed.
