ADDITIONAL INFORMATION

I can confirm, but that's a movit only (GPU acceleration) issue. You can solve it by disabling it in Kdenlive Settings > Playback.

One developer is currently looking at movit stuff trying to fix and improve it.

No that's why I use kden. For the hardware accel. Thanks for the fix in the meantime!
