SUMMARY With the desktop effect "Translucency", windows are transparent while they are being dragged. If, however, the virtual desktop is changed while dragging a window, it won't be translucent anymore, until it's released and dragged again. STEPS TO REPRODUCE 1. In Desktop Effects, enable Translucency 2. Make sure that virtual desktops are set up. 3. Drag a window, and while dragging it, change virtual desktop (it's easier with Switch desktop on edge (in Screen edges)) OBSERVED RESULT The window won't be translucent anymore. EXPECTED RESULT The window should stay translucent.
