It can be worked around by deselecting "Allow the window manager to control the windows"
Nice solution! The only last problem is that when you use "Allow the window manager to control the windows" deselected you lose the "stay on the top" behavior of the instruments windows, so you can't access to instruments if you enlarge the image window.
