black preview

Steps to reproduce :
- set the previews to the default setting "only for shown windows"
- open firefox (or dolphin, or konsole, or any other applications, but not a media player)
- hover the mouse on the firefox tab until the tooltip appears
- minimize the window by clicking on the tab
- move the mouse over the tooltip
- move the mouse back to the firefox tab

Actual result :
- the preview in the tooltip turns black

Expected result :
- the preview should be the last visible state of the window (just like the alt-tab widget) or the firefox icon

Additional infos :
- intel gpu in modesetting
- opengl 2.0
- media players are not affected

It doesn't happen anymore since the last update.
Now there is the icon of the program.

Thanks.
