This just happened in one of my GRID 2019 videos I captured, but wasn't happening before. I'm wondering if there's a SP problem with the latest version of GeForce Experience. I might completely uninstall the 461.40 driver and GFE and see if reinstalling 461.40 fixes it. Seems to me this happened after GFE installed a new version on it's own when I opened it up a little while ago.
