This script uses python api for RenderDoc to find a first draw call which, when called several times with the same input, gives a different output. This indicates an issue in the application or in the driver. The script was made to help with the investigations of bugs in Mesa 3D graphics library.

The script requires renderdoc python module (renderdoc.pyd or renderdoc.so depending on your platform) and main renderdoc library (renderdoc.dll or librenderdoc.so).

Usage example:

LD_LIBRARY_PATH=/path/to/renderdoc/lib python3 flaky_finder.py \
 --python-module=/path/to/renderdoc/py/module --rdc=capture.rdc

Transferring capture: |████████████████████████████████████████████████████████████████████████| 100.0% 
Draw Calls: |█████████████████████████████████████████████████████████████████---------| 91.7% Checked

It's possible to specify remote server with --host.
