Bug 493721

SUMMARY
The software hangs at allmost every action.

STEPS TO REPRODUCE
1. Open aplication, (it openes fast, the UI loads perfectly) after that i have about a minute of hang until i can do any action
2. Insert a single image, small or big file size, anything into the bin, hangs again for about a minute, drag it to the timeline, another hang, scrubbing the timeline allmost allways hangs on every click.
3. triming and compositing, transision wiping si fast as it should, exporting via CPU or GPU is fine without an issue

OBSERVED RESULT
4. I did not setup any presets, or changed anything from the default first time boot.
5. Its a first time Kdenlive has run on this windows 11 PC, drivers and OS updates ar updated, it does the same with or without running it as administrator, compatibility mode
6. Manual says that changing to OpenGL backed could help, there is no such option in the application settings, no ideea how to do that;
7. The application doesnt crash it just hangs at allmost all actions, even if the action has been allready use prior.

EXPECTED RESULT
