Anybody else seeing "bleed through" of default scenery into third-party in SU11?

I’m getting this in both FeelThere TIST and Airworthy TNCM.

Are you using DX11 or 12?
DX12 has been giving some users runway texture issues, this doesn’t quite look the same, but it may be related.

For TNCM, you could also try deleting the default TNCM through the content manager.

It’s DX12. I’ll try the TNCM fix, thanks.

You could give DX11 a try as well, just to see if it cures the issue!
