[PlayerSettings] After changing Graphics API some UI elements do not respond correctly




Priority: 7Not yet prioritized for a release


Severity: 4Minor or cosmetic issue

After changing Graphics API (Seemingly any to any) some UI elements do not respond correctly.


1) The scene view window does not respond to MMB (Pan) or RMB (Rotate) until an object is selected or an actual button is pressed
2) Tabs for windows which are docked with other windows are unresponsive

Repro Steps:

1) Open project and scene "2"
2) Change Graphics API (Player Settings)
3) Attempt to pan or rotate scene view (MMB/RMB)
4) Attempt to select a docked tab for a window
5) Select an object or press a button on the UI
6) Re-attempt steps 3 & 4

Whilst minor, this behaviour could be mistaken for the editor hanging.
