Boeing 307 causing gray trails in others aircraft contrails

ISSUE DESCRIPTION

Description of the issue: Installing the Boeing 307 causes a thin trail (assuming it is some sort of a prop effect that somehow appears globally) to appear in the middle of every plane’s contrails. This is an issue with the recently released AAU5 Boeing 307 as well as the 2020-native Boeing 307. (See this thread discussing the issue in 2020 where it was narrowed down to the Boeing 307 specifically: Contrails suddenly gray and thin -- how to fix? ). The MSFS2020 versions of the Boeing 307 are not installed in my 2024.

FREQUENCY OF ISSUE

Every sim launch/flight unless the Boeing 307 is not installed.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Install Boeing 307 from Marketplace

  2. Fly up to altitude where contrails will form with an appropriate plane and observe the contrails

    FWIW, It does not seem to matter if the aircraft is streamed or installed locally.

    1. When uninstalling (or reinstalling) the Boeing 307, a sim restart is necessary afterwards for 2024 at least.
    2. Repeat the steps upon relaunch and contrails return back to normal

YOUR SETTINGS

What peripherals are you using, if relevant:

[PC Only] Are you using Developer Mode or have you made any changes to it? → Used only the Aircraft Selector tool to switch planes without returning to the main menu. No changes.

[PC, MSFS 2020 Only] Are you using DX11 or DX12? → DX12

[PC Only] What GPU (Graphics Card) do you use? → RTX 5060 Ti

[PC Only] What other relevant PC specs can you share? → Windows 11, 32GB RAM, i5-12400F

MEDIA

Again, it happens regardless of the plane, just picked two planes for the screenshots.
In the below screenshots, the Boeing 307 is installed:

In the below screenshots, the Boeing 307 is disabled/uninstalled:

Hello, noticed the same weird contrails shape as if there is an oil, fuel or hydraulic leak…

Seems to be whatever the aicraft (screenshot below with default FS2024 iniBuilds A330):

By any chance do you own the Boeing 307 in FS2024 ?. If so see: Boeing 307 causing gray trails in others aircraft contrails. This type of artefact can be due to another aircraft/mod.
Have you tested with all your addons (if any) disabled (Marketplace/community) ?

Can’t say right now, I’ll check when my flight is done :slight_smile:

Yes, was linked to the b307… All good now after deactivating it!
Now this needs to be fixed by MSFS dev team :slight_smile:

I’m OK to merge this thread with the one you mentioned :slight_smile:
