I have two pictures in the directory: A.jpg (WxH = 12360x9420) and B.jpg (13632x2938). When A is double clicked in vlc, vlc tries first, after failing doing anything, vlc go straight to B.jpg. When B is double clicked in vlc, vlc shows a thumbnail on the lower left corner, then shows a progress bar for 10 seconds and stops.
Here is the debug message on A.jpg

Here is the debug message on B.jpg

The messages were generated with VLC 3.0.6 on Ubuntu 18.04.2.
