Sorry for the late response.
We are sorry but we do not offer a debugging tool at this moment.
Could you please try recording with Bandicam 5.0.2 and check if the issue still exist?
If you have the same issue, please attach the DxDiag.txt file?
If you don't know how to get a DxDiag.txt file, please follow the 6th step on the page below.
Also, please let us know which recording mode on Bandicam you used.
