Please describe your issue in as much detail as possible:

Launching Big Picture Mode GPU hardware acceleration works as expected, if I close BPM and relaunch BPM (doesn't matter when) then GPU hardware acceleration does not work and the UI is extremely laggy at around 2fps. It never recovers, even when closing and restarting steam.

Steps for reproducing this issue:

1. Launch Big Picture Mode
2. Close Big Picture Mode
3. Relaunch Big Picture Mode
4. No hardware acceleration
