Bug ID: 37035 Summary: Microsoft Office 2010 / 2007: Restore window from tray is broken if 'Keep window thumbnails' is set to Always in KDE. Product: WineHQ Apps Database Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: appdb-unknown Assignee: wine-bugs@winehq.org Reporter: eierfrucht@gmail.com
All Microsoft Office 2007 / 2010 applications exhibit this behaviour with Wine 1.7.23 and all previous versions going back to wine 1.4, there also seems to be no connection to the currently used Distribution, Kernel or KDE version.
1. In KDE System Settings, set 'Keep windows thumbnails' to 'Always (breaks minimization)'
2. Minimize an Office 2007 / 2010 app window.
3. Try to restore it and all you will get is a tiny square in the left top corner of the screen.
4. Force showing KWin's native title bar on top of Office 2007 / 2010 windows, minimizing with KWin's embedded title bar button works without triggering this issue.
I have observed this behaviour on Arch Linux and Kubuntu since very long ago. Switching to different Kernel, KDE and Wine versions does not affect it. I know that 'Keep windows thumbnails' used to break minimization for several apps, but this option is pretty much vital to KDE's Present Windows function and most task managers that use window thumbnails. So far, Office 2007 and 2010 are the only apps suffering from this issue that I'm aware of. I have never witnessed 'Keep windows thumbnails -> Always' breaking any other app.
