--- Comment #3 from uvizoceke-8...@yopmail.com --- Same issue, although everything worked fine a few days ago. Project monitor, or clip monitor, stay black when i click the "play" button. I tried to reset settings : problem still there. I tried to delete kdenlive config folders in my home directory : problem still there. I tried to create a new project, and only insert a videoclip without adding any effect : problem still there. (so no relation to bug ID 367686) I run Kdenlive 16.04.3 on up-to-date Fedora 24 MATE spin with 4.7.2-201 kernel and NVIDIA 367.44 proprietary drivers for my GeForce GTX 970. I tried with kernel 4.6.7-300, problem still there. Please find my package manager history in attachments. Does one of these transactions could have created the problem ? They are the only system modifications I did between the moment the project monitor in kdenlive worked and the moment it doesn't work anymore. Maybe xorg server package updates ? -- You are receiving this mail because: You are watching all bug changes.
