Black polygon that crashes the game

[Tafara]

There are some regions where if I go I start seeing black polygon tearing. And it also crashes sometimes the game with an error but not always. How to fix this issue. Hard to see and play the game this way for quests that need me to be in those regions.
```
Error:

I am using wine on Ubuntu 24.04

Renaming WTF folder to WTF.backup and starting the game again fixed it.
