From what I and a few others stated, yes Stereo Mode eliminates the issue. I t appears the issue has to do with the new Single Pass Mode. Just be sure to pick Stereo Mode and the next time you launch P3D it remembers the last choice through a config setting.
I have since rolled back to v4.1. I believe the latest FI verse 1.92 works fine with both P3Dv4.2 and v4.1
