So when you load a world with RTX ray tracing pack on, the panorama will turn into a very laggy screenshot of when you saved the map last time, but the colour is inverted and much more saturated, also with some glitchy effects.
To reproduce:
Launch MCPE with an RTX graphics card
Open a world with RTX ray tracing pack, if don’t have, get one on the marketplace
After joining, leave.
Rejoin the world
It sometimes come out, you can see the panorama being replaced with a glitchy version of what last time you played, otherwise it lags.
ps: If you load another ray tracing world, the panorama will not change to the last screenshot of the world you are loading into, instead, it will show a screenshot of the previous world with ray tracing even if it uses another ray tracing pack.
Screenshot coming soon
