Black dropshadow showing underneath certain sprites

I forgot to report this a while ago, but in the software renderer there seems to be dropshadows appearing underneath certain sprites, most of them being these "particle" actors (blood, bullet smoke, etc.). Unfortunately, I do not know any more details than this.

Here is an archive isolating the blood particles displaying this problematic behavior: Link

Apologies for the bump, I thought it would be appropriate since this may provide additional insight. I've found that this particular effect happens on decals as well. As you can see, the gib decals (they are only "sprayed" by gibs which are in turn, spawned by xdeathing monsters) as shown in Dead Marine are also a victim of this strange bug. The "shadows" are once again highlighted in green below:



I wish i could provide more details, but after some time of testing and fiddling with my own mods, I just can't seem to figure out what triggers this.

When did this start happening? It looks a sampling error or maybe the spans being off by one.

Unfortunately I don't quite remember that well, but roughly a year and a half ago?
