Two crashes fixed. Stopping and starting FlatVR a few times in one sitting could bring the app down - a leak on every stop, introduced in 1.53, now gone. And restarting SteamVR while FlatVR was open could crash it the moment the runtime went away.
The screen no longer judders or briefly changes size while you turn your head. Each frame was rendered for one head pose but handed to the headset stamped with a slightly newer one, and the compositor corrected the picture the wrong way - invisible while you held still, and worst on streamed headsets like Quest over Virtual Desktop. The two now always match.
Crash reports also carry better diagnostics now, which is how both of these crashes were found - thank you to everyone who pressed Send.
