Cannot mouse turn after teleport

Anyone has a solution on this?

The first second or two after you teleport, you can't use right mouse button to turn your character (but you can already move around).

My guess is that this is due to the fact that the camera is locked while the screen is still fading in, but the fade in is linear with respect to brightness, which means that the last second or so isn't discernible to the human eye.

The result is that the human eye thinks the screen has faded in completely while the game is still adjusting the brightness, so it locks the camera. Solution would be to stop locking the camera during scene changes if we have the relevant option set.

Or anyone has a workaround for this annoying behavior?

Some online games have used additional loading screen as workaround.

The problem is that after the loading screen, the player can move, but cannot mouse turn.

I'm not sure I understand the intention of your reply.
