Description Mark Bethel 2018-04-09 03:50:49 UTC

Application: kdenlive (17.12.2)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.15-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
Whenever the Movit Library is enabled, kdenlive becomes very unstable, this has been an issue for a long time for me. However with GPU acceleration disabled, kdenlive gains its stability back.

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Reported using DrKonqi

Comment 1 zvezdin 2018-09-13 00:05:49 UTC

I can confirm that this is an issue on my side as well. Running on Arch, GTX 1060 6GB with proprietary nvidia 396.54-3 driver. Kdenlive is nearly unusable with GPU acceleration on (a pretty much needed feature for such a professional-grade program).

Comment 2 zvezdin 2018-09-13 00:11:26 UTC

Created attachment 114922 [details]
New crash information added by DrKonqi

kdenlive (18.08.1) using Qt 5.11.1

- What I was doing when the application crashed:
Navigating through the timeline.

- Custom settings of the application:
GPU acceleration with movit

Unfortunately, Movit is not stable. See here: Bug 380019
Disable it for the time being.
