Alt tab fps drop bug still a thing

Alt tab out of the game, get back, framerate is now fubar. Resolves itself by flicking reduce buffering off and back on again. That is, until you alt tab again. Same bug has been reported for years, but it’s still a thing.

To quantify the problem, here is how it affects my performance in a controlled benchmark (timed benchmark of the same replay, logged with frameview).
