Many covers are no longer displayed correctly

[Prisme]

Hello,

I am on version 10.9.2 with docker in Debian. Since the update, many covers are no longer displayed correctly when I open a film file. The covers are displayed correctly in the library, but when I click on certain films to access its file, the cover is nothing more than a square.

I use custom CSS code, but with or without this code and after restarting the application, the problem is the same. I never encountered this problem before the 10.9 update.

Below, two screenshots to illustrate the problem:

The cover is displayed correctly in the library:

   

And once the film file is opened, it is displayed in the form of a square:

I have this issue as well, but it only seems to happen with a couple movies, not the majority. Very weird.

What library type is in? A plain Movies type or a mixed type?

What library type is in?  A plain Movies type or a mixed type?

A plain movies library. Apparently it affects covers with a certain aspect ratio.

For my part, I have thousands of rare films for which I had to find covers here and there or make them myself and many are affected.

But I'll give an example using images from TheMovieDb:

With the choice of the left cover, everything is fine:

   

   

But with the choice of the center cover, here is the result:

I can confirm the same behaviour. Standard, un-mixed Movie library. I've only seen it happen on one movie. I switched to a poster with a more standard aspect ratio (1000x1500) and it now displays properly.
