Problem with map visibility/line of sight.
I've played Rome 2 with DEI for a long time, but I took a break for a while and I'm just now getting back into it. I've had a weird bug persistently happen where on the every single battle map, my line of sight is significantly reduced. I can't even see from my deployment zone into the enemy deployment zone. It's not hidden by terrain either, as it happens on flat desert or plains maps as well. So an enemy army just kindof pops into existence about 200m in front of my army. This kinda breaks the whole campaign for me, because I'd have to use 3 or 4 cavalry units just to see the map. Large battles with reinforcements or naval battles are extremely annoying with the visibility reduced like this.

So I tried verifying my files to see if that made a difference. No change.
I turned off all mods, and the game works perfectly, map visibility back to normal.
I deleted all mods, uninstalled the game, deleted the game folder, and made sure I couldn't find any other Rome 2-related folders. Then I reinstalled the game and checked it. Still worked fine in vanilla.
I downloaded the latest version of DEI from the steam workshop, and no other mods. I double checked my load order, my in-game settings, and the visibility bug is still there.

I know this is probably my PC and not the mod itself, otherwise the community would be talking about it, but I'm at a total loss for what to do. I tried other otherhaul mods like Wars of the Gods and Radious, and I haven't had the same bug. DEI is my favorite overhaul mod, and I'd really hate to not use it going forward with TWR2.

Can anyone help me figure out what the heck is wrong and how to fix/reset it?
