Creative Mode: Crash and return to Windows screen when scrolling inventory

Win 10 Edition always crashes when I'm scrolling through inventory in creative mode('decorations' immediately, 'search' when scrolling for about 3 seconds, all others are ok). It starts to freeze and 1 second later I'm back on Windows Screen.

No difference between a saved game or a newly created world or with/without texture packs. Walking around is fine, building structures work, travelling to nether is ok...This only happens in Creative mode.
