Bug ID: 521706
Summary: Kdenlive 26.04.2 crashes on project creation (preset
selection) with NVIDIA RTX 5060 Ti — workaround:
QT_OPENGL=software
Classification: Applications
Product: kdenlive
Version First 26.04.0
Reported In:
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: grave
Priority: NOR
Component: Setup & Installation
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Description:
Kdenlive 26.04.2 crashes consistently when selecting a project preset in the
new project dialog. The application
launches correctly and the preset dialog appears, but as soon as a preset is
confirmed, the process crashes and leaves
a stale kdenlivelock file in %TEMP%, preventing any further launch until the
lock file is manually deleted.
Reinstalling Kdenlive does not fix the issue. Resetting the configuration
(kdenliverc) does not fix the issue either.
Steps to reproduce:
1. Launch Kdenlive 26.04.2
2. In the new project dialog, select any preset
3. Kdenlive crashes immediately
Expected behavior: Kdenlive opens the project with the selected preset.
Actual behavior: Kdenlive crashes. A crash dump is generated in
%LOCALAPPDATA%\CrashDumps\kdenlive.exe.*.dmp.
Workaround: Launching with QT_OPENGL=software prevents the crash:
set QT_OPENGL=software && kdenlive.exe
System information:
- OS: Windows 10 Pro 10.0.19045.6466
- Kdenlive: 26.04.2
- GPU: NVIDIA GeForce RTX 5060 Ti
- NVIDIA driver version: 32.0.16.1062 (installed 2026-06-11)
- Secondary GPU: AMD Radeon (integrated), driver 32.0.21036.18
Notes:
The crash dump shows the crash occurring inside NVIDIA driver modules
(nvwgf2umx.dll, nvcuda.dll, nvd3dumx.dll),
suggesting the issue is related to OpenGL/Direct3D context initialization
with the current NVIDIA driver. The
application worked correctly with a previous driver version. The
QT_OPENGL=software workaround confirms the GPU driver
is the root cause.
Crash dumps available on request.
