GoldenCheetah crashes on exit or when saving files - GoldenCheetah/GoldenCheetah GitHub Wiki

I you are experiencing crashes when imported files are saved, i.e. when they already been validated, on exit or other situations not related to the files being imported, the likely reason is a bug in your display device drivers.

GoldenCheetah uses OpenGL and this may trigger display drivers bugs not affecting other applications.

The first recommendation is to update your display device drivers.

An alternative is to disable OpenGL, this can be done setting the environment variable QT_OPENGL=software, this makes QT doing pure software rendering avoiding most driver issues, at a performance cost.

On Windows another option is to set QT_OPENGL=angle to map the OpenGL calls to DirectX calls - so that also no OpenGL driver is used.

New for v3.6: angle is used by default on Windows, unless you start GoldenCheetah.exe with --no-angle command line option.
