Problems after adjusting camara angle

After adjusting the camera angle using the right mouse button the mouse pointer stays hidden.
Also the camera angle can not be adjusted anymore, have to re-login to be capable to do this again. For one time.

The mouse pointer can be brought back by moving over an input box. But it only stays visible when the input box from the chat window is used. Unhiding the mouse pointer by using input boxes of windows that will be closed after use (eg. vendor ui) the mouse pointer will be hidden again after this window is closed.

This does not happened on the current QA build. Everything works normal there.
I do not want to wait a full month when R60 is released, if possible.
