Please describe your issue in as much detail as possible:

When playing a game where there are effigies in the game, and they are on-screen, they cause severe rendering artifacts. It doesn't happen at the start of the game, but I haven't found a particular trigger, it just happens "after a while".

This started happening after summer update, https://www.dota2.com/summer2023, presumably somehow related to the rendering updates that occurred then.

Steps for reproducing this issue:

  1. Play a game.
  2. Have a effigies in a base.
  3. Towards mid or end game, scroll an effigy into view.
  4. Profit from massive rendering artifacts.

Today I played two whole games with no rendering issues from effigies thought for a minute maybe the latest update, which caused a shader refresh, might have fixed the issue. Unfortunately it just happened to flags instead. image

I tried the different graphics settings today to see if I could pin down the cause to some particular rendering feature, but even with the "fastest" graphics settings, I still had the same issue.

I have replaced my aging GTX 770 with a GTX 1660 Super instead, and the problem has gone away. Beyond the hardware upgrade this also let me upgrade the driver from the 400 to 500 series, so the change is pretty big, which means it doesn't help much in narrowing the issue down. At least it works for me now. :)
