When enabling Seated Passengers on the PMDG 737 (tested 700 and 800 variants) it causes the cockpit to go blurry and the rest of the plane to go missing. I am attaching screenshots.
The default PMDG liveries work fine, but even the liveries from the PMDG ops center do not work.
Disabling Seated Passengers in the FSDT installer resolves the issue.
