This reverts commit e946e6895a8517a887ac246905e0769edd766fcc.

It clears the duplicate show() and hide() too aggressive in
handleDeferredTasks() and can cause visible states out of sync between
qt and system(x11) when user switches visible on and off very
frequently.

This change also reverts 28138aa80a14279a72af2818f5bbbaa670283964.
