Kdenlive: "Cannot initialize Movit's GLSL manager, ..."

[peter_b]

[PROBLEM]
I wanted to enable GPU processing in kdenlive (on Xubuntu 16.04, 64bit), but got this error message instead:

Cannot initialize Movit's GLSL manager, please disable Movit

[SOLUTION]
Haven't tried it yet, but starting kdenlive in a terminal, gave me the following information:

Shortcut for action "rename" "Rename" set with QAction::setShortcut()! Use KActionCollection::setDefaultShortcut(s) instead.
Removing cache at "/home/pb/.cache/kdenlive-thumbs.kcache"
Movit system requirements: Needs at least GLSL version 1.30 (has version 1.2)

Hm.... version 1.30...
