Cursor missing in Unity 5 editor

I made a video explaining what happens.

when i leave the game window in the unity 5.2.2 editor - the mouse curse which is hidden in the game - stays hidden. it didn’t happen in unity 4

is this a bug in unity ? was it reported already?


This often happens to me on v2017.2.0xb6 Linux Personal, but worse, afterwards the mouse is completely invisible in the Inspector panel following a Play preview and sometimes other panels too. I can only stop the Play preview with ctrl+p.

To get the cursor back in the Unity UI I must reset the overall layout: Window > Layouts > *preferred layout name.
