I just noticed something which might help reproduce and/or narrow down this bug: I have two monitors connected to my graphics card, but, since I usually only use one of them, I didn't change the default setting of "Same image in all monitors" (in the Monitor preferences). Now that I have unchecked this option, the panel works as intended.
