Duplicated windows

[drobosoft]

Hello,
after using Windows catalogue - all desktops (thhrough Hot Corners), all windows are duplicated to the active desktop.
Steps to reproduction:
- activate windows catalogue (all desktops) in the Hot Corners settings
- move mouse cursor to the corner where the catalogue is activated
- click any window or press esc
- all windows are duplicated to the active desktop

There is another issue with Task switcher with some applications (eg. Unreal Commander). Some windows are visible twice in the preview (once as Unreal Commander and the second as Unreal Commander v096 - <username>)

Cheers,
Robert
