And it happens also when I close menupopup(App button menu and contentarea context menu etc.) which overlapped with the control each other.

It seems to happen only in Window Clasic Style.

If disable D2D and D3D9 both, It still happens in Window Clasic Style.

If enable one of them or both of them, it does not happen.

It only happens in case of  disabled D2D and D3D9 both(Tools > Options > Advanced > General > Uncheck "Use hardware acceleration when available").

See attachment 457868 [details] 
In this case, file path in 3rd input box is invisible,In other words I may post the file which I do not want. I think that there is a problem in the privacy.
