Hi,
Problem: Window capture is white blank (Firefox)
Graphics card: NVIDIA 1050Ti
Fix: It seems Firefox has to be set on high performance setting in NVIDIA control panel.
NVIDIA control panel > Manage 3D settings > Program settings > 1. Select program (Firefox) > Power management > Prefer maximum performance
This worked for me :)
