Your EFB goes white/pink when the side window is opened.
If your EFB looks like the below image, this is caused by the Lock Interaction Mode. This is a bug caused by Asobo that breaks interactive textures when the highlighting kicks in.
To resolve this, navigate to MSFS General Settings -> Accessibility -> User Interface -> Cockpit Interaction System and set this option to Legacy.
If you prefer to use Lock mode. We have now added a new interactions.xml which you need to swap out and this should resolve the issue. This does remove the blue highlights, however.
- Go to: Community\fnx-aircraft-320\ModelBehaviorDefs\fnx32x\Templates
- Rename interactions.xml to interactionshighlights.xml
- Rename Interactions_No_Highlight.xml to Interactions.xml
Then open up MSFS and the issue should be resolved.
