(Fixed) Issues with SteamVR beta 1.15.1

I just want to let you know that in fpsVR some functions (resolution detection button, screenshot functions) may not work correctly if you are using SteamVR beta 1.15.1
I expect it to be fixed in the next SteamVR Beta update. I notified Valve about the bug I found.

Update: Fixed in SteamVR beta 1.15.2
