Do you have the same issue if you follow the OP’s steps to reproduce it?
• yes

Provide extra information to complete the original description of the issue:
• When flying, rain is moving vertically from the bottom to the top on all the surface of the left window
on the right window the rain is also moving vertically but from top to bottom on a large surface, just it is moving in the opposite direction into the red square as indicated on the screenshot

In flight, rain should move from the front to the back of the window
When plane does not move (on ground) rain should fall vertically from top to bottom of the window.

If relevant, provide additional screenshots/video:
