Created attachment 9028 Screenshot of rendered window while moving If compositing is enabled and window decoration opacity is less than 100% (ie. translucent frame), the move/resize function seems to disobey the "Hide content of windows" settings. Screenshot attached. Old bug, has been around since at least XFWM 4.12 (possibly older), still present in the Git master.
Created attachment 9029 Screenshot of rendered window while resizing
To clarify about resizing, when resizing the window contents move despite the "Hide content of windows" settings. When moving, the contents also move (disobeying the settings) but get clipped at the region where the window is located before moving. The move/resize appears to work fine when the opacity of the window decorations is set to 100%.

This should now be fixed. Please note this is minor visual glitch, no need to set this as a major/critical issue.
