GTX 10 series cards show pink flashing glitch

We recently released a demo for our game The Mound: Omen of Cthulhu on Steam, and we have consistent reports from users who ran the game on NVIDIA GTX 10 series cards that the game displays pink flashing textures on various objects in the game.

We have not had any similar reports on other cards.

The game is using Unreal Engine 5.7.4. We suspect the issue is related to Nanite on this specific version of Unreal, since we use it on all configurations and users have reported no issues with other UE 5 games.

Are there any known issues like this? And if so, are there any known fixes or workarounds?

Hello,

I was unable to find any known related issues. If you can provide a log and a GPU capture (NSight, PIX or RenderDoc) when the pink texture is visible that could help us investigate the issue and provide more suggestions.
