I suspect you were using libdrm 2.4.60. Use either .59 or .61 and that particular error will go away. That said, I also see the tooltip fail in chrome on a GF108 (nvc0 driver) for a few versions of chrome now.
Thanks! I was indeed using libdrm 2.4.60. Downgrading to 2.4.59 solved the problem of the solid black menus, so at least my Chromium is usable again, but I still have corrupted tooltips sometimes.
