The situation seems a lot more difficult to reproduce with tool-bar-mode on (I usually keep it off) -- haven't managed so far. But without the tool-bar, I reproduced it a bunch of times over the last couple of minutes. Hovering the mouse over the mode-line does trigger the necessary redisplay. Alt-Tabbing to another window and then back also does that. Is that relevant? Simply moving the mouse (not over the mode-line) doesn't help. The refresh can also happen on its own, in 1-2 seconds.
