I just installed splice from the humble bundle, and I get a blank screen on startup. I can hear the audio, and if I move my mouse around, I can hear the menu items or something changing.
I have an amd radeon HD5800 series. I'm using the fglrx-updates driver on 12.10, fully updated.
Any ideas of things to try? Full screen or windowed, I get a blank window. Also, other GL games are running just fine.
