- vr_compat.h: GetProjectionMatrix / GetEyeToHeadTransform called with Microsoft's member ABI on MinGW builds
(SteamVR is built with MSVC; the hidden return pointer goes after this): the first frame crashed there.
- When SteamVR asks it to quit (a game, room setup), Frame Home leaves at once instead of waiting for a load (SteamVR
killed it after 5 s).
- The panel keeps SteamVR's home app running on a PC: SteamVR doesn't start it again after it stopped on its own.
- Logs on Windows: the environment and the panel always write logs/frame-home.log and logs/frame-switcher.log (SteamVR
gives them a hidden console); the panel logs to a file on the headset too now. A crash writes the exception and the
stack's return addresses there.
- Tested on SteamVR's null driver: Frame Home started by SteamVR as its home app, the panel with it, SteamVR's
background made from the home, a crash recovered in seconds, 0.79 ms GPU at 1976x1976 per eye with 4x MSAA.
