Comparing the outputs of the game in both cases -

 diff et-out-window et-out-full
< XFree86-VidModeExtension: No acceptable modes found
---
> XFree86-VidModeExtension Activated at 1280x1024

Yes could be - I guess my original workaround of starting both screens @
1024x768, diabling TV then xrandr monitor to 1280x1024 maybe only worked
because of the xrandr res change.

One thing I forgot to mention about when I do the above, is that when the game
quits I end up back @ 1024x768, locked in the bottom right of a 1280x1024
desktop.

This happens with openarena as well - the games are really running at 1280x1024
- I can see that with OSD on my monitor.
