Just tested the PTR.
Both of the issues seem to be fixed.
1 - rawMouseEnabled 0 (default). There’s no auto camera movement and the cursor hasn’t become stuck after about 10mins of clicking on Troll NPCs in Senjin Village.
2 - rawMouseEnabled 1 (to counter the old snap bug and generally have snappier mouse movement). There is no auto camera movement while moving and the sticky cursor issue doesn’t exist.
If you go on the PTR to test this make sure you go into the interface options and disable sticky targetting and any auto camera movement in the camera settings. These two options can make it feel like the camera is doing its own thing when you are testing this bug.
There’s possibly a little bit of stickiness in the vertical direction but it doesn’t feel super bad. Need others to go on PTR to comment.
