He Folks, I'm using Kdenlive 18.12.2 on Windows 10 pro.

Before yesterday I was able to edit Video projects with at least 3 video tracks and 2 audio tracks. Working felt super responsive and the fps counter on the monitor screen was most of the time 30 fps.

I don't know what happened but since yesterday my Kdenlive has changed. When I open my project, the monitor screen shows me a green picture with reversed letters on it for some seconds before displaying an actual frame. Also the playback stutters so much (fps still shows 30 fps though) that I can not work anymore. This now happens also if I create a new project with a new video file with a low resolution (756 x480) and when I just try to play it in the clip monitor.

Is anybody out there who knows what caused this strange conversion of my KDEnlive from super performant to unusable over night?

Maybe you got the Win10 1809 update. If so you have to update all drivers for audio and video.

Intel driver update you can do with this updater: https://downloadcenter.intel.com/en/dow ... -Assistant

This sounds interesting. yes, the only thing that has changed was an update since yesterday. Thanks @Merlimau, I'm updated the drivers via your link. And... kdenlive works like a charm again! You`re an angel.

Glad to hear it works. Could you mark the thread as solved? So others see the solution.
