Ubuntu 16.04 + Wine + Alt

[antrix2k]

I have clean installed Ubuntu 16.04, wine 1.9 and Steam (non linux version). I want to launch Space Rangers HD A War Apart (and some other game), but there is one problem... when i press ALT key - some games minimizing, some games freezeing. I think that problem in Dash panel with Alt hotkey and i have disable all Alt hotkeys... but there is no changes at all. Games still freezeing (or minimizing) on Alt keypress. On Kubuntu 16.04 work perfectly. How can i fix this problem?
P.S. Sorry for my english, i'm from ukrainian community.

You have to change the Dash panel shortcut: System settings > Keyboard > Shortcuts
