I would imagine this is because you're not offloading anything at that point
and running it on the IGP.

>I don't recall having any problems under KWin or Xfwm4.

This is because KWin defaults to Xrender, and Xfwm4 is *only* Xrender. xcompmgr
works fine, too, as do the default settings on Compton.

If you try this on:

* GNOME3
* Cinnamon
* Compton with --backend glx

You will get a black screen.

However, if the screen is *not* full screen, you can resize the screen and the
image will appear (such as with glxgears or glxspheres).

Unfortunately, in screens that are "full screen windowed", as are many Wine
games, it still shows up black and there's no way to resize the screen in order
to make the image show up. In any case, that's not really an acceptable
workaround because it just shows that there's something wrong with PRIME
offloading that causes this odd behavior on GLX-based compositors.
