What kind of system is this, what OS?

It's a notebook with Windows 7, no dual GPU, only a Intel HD3000. I'm not sure if resizing fix it, but I'll try the next time. I know that hovering over the link for more information on the bottom left corner, make it appear.

I think I am also experiencing this bug but on a different hardware: a desktop with Win 8.1, i7 2600k CPU with Nvidia GeForce GTX 660 Ti - when leaving Nightly running for a long time and not updating it, the popup/window of the upgrading is blank when brought to view from the task bar.

Jeff, is the popup window using the same compositor type as the rest, or are we in basic layer manager at that point?

It seems bug 1237617 fixed this issue.

Sorry for the noise, I just got this again, so not fixed.
