VLC does not center video and uses "wrong" ratio

[SlowMotion]

Seems the problem only occurs if the window size and the video size is not matching.

If the window width is increased, left and right black areas appear (correct).

But when the window high increases the bottom of the video is cropped, the higher the window gets, the more pixels get cropped.


Hint : I am using KDE with X11 as wayland is freezing my desktop.
