Subject: force pixmap clear when hiding an x11 window
X-Git-Tag: upstream/0.20.0~229
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bb557cbf9f9d903a4f9086a8f4fe8ca4b2bbf9d5;p=platform%2Fupstream%2Fenlightenment.git

force pixmap clear when hiding an x11 window

failure to refetch this upon remapping the window will result in
a broken pixmap which cannot be rendered
