Movies and media are tiny, just 5 minute screen demos. Performance is fine. But the "crashes" make it maddening to use. This occurs across three computers. Every minute or two, when some control on the screen is changed (no pattern detected), the program hangs for maybe 30 seconds and the Windows Problem Reporter fires. These appear throughout my event log. Faulting application name: kdenlive.exe, version: 0.0.0.0, time stamp: 0x68d02ee1 Faulting module name: Qt6Core.dll, version: 6.9.1.0, time stamp: 0x68a48b66 Exception code: 0xc0000005 Fault offset: 0x000000000025fccc Faulting process id: 0x26E0 Faulting application start time: 0x1DC37C9B7D85B5E Faulting application path: C:\Program Files\kdenlive\bin\kdenlive.exe Faulting module path: C:\Program Files\kdenlive\bin\Qt6Core.dll Report Id: ed65b878-1e6f-4842-99fd-aa35eee5986b Faulting package full name: Faulting package-relative application ID: STEPS TO REPRODUCE 1. Start program. 2. Put a small clip into timeline 3. Do just about anything OBSERVED RESULT Faults every few or even every minute. No data is lost and the program has not actually fallen down. It picks up where it left off. EXPECTED RESULT No hangs SOFTWARE/OS VERSIONS Windows: Windows 11 macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: Qt Version: Kdenlive: 25.08.1 Package Type: Unknown/Default MLT: 7.33.0 Qt: 6.9.1 (built against 6.9.1 x86_64-little_endian-llp64) Frameworks: 6.18.0 System: Windows 11 Version 24H2 Kernel: winnt 10.0.26100 CPU: x86_64 Windowing System: windows GPU: Movit (GPU): disabled Track Compositing: qtblend ADDITIONAL INFORMATION
Can't reproduce on Linux 25.12.1 Any chance you can try with latest release 25.12.1 ?
Created attachment 189251 [details] attachment-3448101-0.html I stopped using Kdenlive because of stability on Windows (across a few computers) - though it was my preferred software. Let me install it again and try to reproduce with more details.
