CH47D Heat Plume?

Hi

This is a weird one…

I have installed the orbx pac p-750 xstol which was working just fine.

But when I bought and installed the CH47D I noticed the heat plumes on the orbx pac p-750 xstol became massive, so large they cast shadows across the cockpit window.

So what I did:

1. I completely removed my MSFS and did a totally fresh, clean installation.

2. I only installed my MSFS "shop" bought aircraft and tested the orbx pac p-750 xstol.
   It worked as it did before I bought the CH47D with a normal-sized heat plume.

3. I then via Contrail installed the CH47D and tested both.
   The CH47D behaved as expected, but the massive heat plume was now visible again with the orbx pac p-750 xstol.

4. I removed the folder called heat-blur from C:......\AppData\Roaming\Microsoft Flight Simulator\Packages\Community\miltechsimulations-ch47d\VisualEffectLibs\effects.

5. I tested the orbx pac p-750 xstol and found the heat blur was back to its normal state.

My question is:

Why would the CH47D heat plume have an adverse effect, or any effect for that matter on the orbx pac p-750 xstol?
