File chooser opened by Qt apps does not show files with uppercase extension
I use Arch Linux, Gnome 3.30, Gtk 3.24.1.
Almost all Qt apps installed on my system uses Gtk3 file chooser to open/save files, some apps can not open files with uppercase extension. For example, I can not open a file named video.MP4 using VLC player 3.0.4 because the file chooser does not show such file. Rename the file to video.mp4 solves the problem. Same problem occurs with SMPlayer, qmmp player and qBittorrent.
