Fresh install of kdenlive Snap from Discover. Launch, after splash screen I get the following: Could not create the video preview window. There is something wrong with your Kdenlive install or your driver settings, please fix it. Click OK and crashes the app. Operating System: Kubuntu 20.04 KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 Kernel Version: 5.4.0-29-lowlatency OS Type: 64-bit Processors: 8 × Intel® Core™ i7-6770HQ CPU @ 2.60GHz Memory: 15.1 GiB of RAM
I have the same crash. I want to add a line above the error log. Before the lines that the original reporter pasted, I also have a 'CRITICAL' error (not sure if the original reporter had this line or not). See below. ``` ** (kdenlive:39472): CRITICAL **: 14:38:45.300: gst_audio_format_from_string: assertion 'format != NULL' failed LC_NUMERIC reset to C Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile) /tmp/.mount_kdenli6O2tyb/AppRun: line 26: 39472 Aborted (core dumped) kdenlive --config kdenlive-appimagerc $@ ```
Delete kdenlive-appimagerc: https://community.kde.org/Kdenlive/Configuration Please try with the current Kdenlive AppImage version 20.08.2 to see if there are any packaging issues https://download.kde.org/stable/kdenlive/20.08/linux/ If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

Now everything seems to be working fine.

Ahh, first I didn't see that you pointed out an earlier version. Now I tested with 20.08.2 instead of 20.08.3. 20.08.2 seems to work without crashing!
