Does anyone have a workaround for item cards not displaying at all for any weapon with lots of special effects?
It seems that item card won't render properly if there's too much lines to display and because of that, I won't see even other items' cards (when comparing, etc.)

Yes, that's pretty annoying. You can see the description if you go to crafting and select the item for upgrade.

I have to unequip the items in the inevntory if I want to see the cards of the other ones which they would be compared to.

Happened to me occasionally - not often.

same here - only way around it that i found is to move the item that has a too long description out of your inventory and to save and reload the game...

Thanks for that tip! It doesn't solve the problem, but now I can at least check my weapon's stats. Yeah, it happens only in specific cases, mostly unique/iconic guns with some mods installed (especially silencer, that adds like 3 lines) I never had to do as much as reloading. It happens 100% of the time with items that have lots of lines of text in their cards, so no amount of reloading will help.

If I browse guns and it's one of my equipped guns that's problematic, I won't be able to see any item cards, but if I browse melee weapons, I have no such problems.
