As is often the case, once the bug is isolated and reproducible, a solution is trivial.
Coming for next Beta.
Thanks, everyone, for your work helping to track this down and eliminate the problem. I've been living with it by resizing the window for a couple of years. But one thing I haven't been able to do is launch O in fullscreen mode, because there was no easy way to resize the window to restore the buttons (note I'm running on a tablet, so no keyboard). With this fix, launching with the -fullscreen option will now provide a fully functional program.
