Insync directly using GPU memory on linux?


#1

insync is the only application on my machine besides xorg and google-chrome that directly uses nvidia gpu memory. This is very weird and seems unnecessary! What is going on with this?

Hi! As per our engineer-- we use Qt5, and the QtWebEngine will use the GPU when available.


Why does Insync make use of my GPU?
