Since the latest SLR update on the quest, the display window has been getting cropped to a sharp rectangular shape, instead of rendering the display in the full field of view available to the quest. It makes the display look similar to when viewing through something like google cardboard.
It enters this mode as soon as the SLR app is launched. And is present through both the SLR interface, and when viewing video content.
I have also noticed that some but not all high res videos (those that don’t quite qualify for that “viewport” option) are now extremely laggy. This is also since the latest update to the SLR app.
I think oculus also recently did an update, so maybe it’s related to that. Hopefully it’s fixed soon as currently it’s a better experience watching via a producers native web player thing, which ain’t ideal.
