Fedora 26 Kdenlive 17.04.2 I downloaded and installed new wipes but they do not appear in the menu. I can see from the forum that there are others with this same problem https://forum.kde.org/viewtopic.php?f=270&t=129025
From the forum https://forum.kde.org/viewtopic.php?f=270&t=129025#p378938 "I had the same problem with 17.04.3 The problem here was that my "/home/marco/.local/share/kdenlive/lumas/" had no subfolders like in "/usr/share/kdenlive/lumas/" There were subfolders PAL/HD If i create a subfolder HD in "/home/marco/.local/share/kdenlive/lumas/" and copy the file then inside it will work. I am not sure if that is a package problem or a kdenlive one" I can confirm this, manually creating subfolder under lumas folder and copying .pgm file there makes it work.
Added a low hanging flag, hopefully someone will pick it up for next release.
