In the search box type "animation effects." Slide the slider for "Animations effects" to off. I still have transparency effects still enabled. This has completely solved my issue and I was having a horrible time with this issue before disabling. It hasn't happened one single time since changing that setting. You will also notice a significant speed increase in changing desktops.
Turning off the animation effects, whilst negatively impacting the user experience, does seem to have the biggest impact for me. Since I did this (with ExplorerPatcher installed), I haven't seen the problem. So a combination of these two things seems to be a reasonable solution until Microsoft get their finger out and fix the bug. Cheers!!
