--- Comment #5 from Robert <rgru...@gmail.com> --- I've updated the nvidia drivers and it fixed the problem, I guess that some modules may not work as intended after kernel update (the problem with black preview in kdenlive appeared after system upgrade using apt). Hope that my post will help someone experiencing similar issue. -- You are receiving this mail because: You are watching all bug changes.
