When I start 0ad (./pyrogenesis -writableRoot) this happens about 20 or 30% of the time for me, kind of random, I'm not sure how to reproduce it yet. This screenshot doesn't show exactly what I see, but the top 10% of my screen is blank. To get the "ok" button to highlight, the mouse pointer has to actually be hovering *above* where the "show this message in the future" text is displays. Then I can click and it will act as if I clicked on "ok" even the mouse pointer isn't on the ok button.
