Well Stardock/Ironclad guys, cool game. Got lots of constructive feedback for you but that can wait until Beta 2, as I know you're mainly looking for graphical bugs.
I do have some for you though. First off the game runs great and very fluid with my graphics card at 1280x960 with graphics on full; however, it seems that I crash about 30 min into a game at random. Doesn't seem to correspond to any particular event. When it crashes, the game locks up and another application comes up called "MiniDump" but I cant ever view that window. I end up having to Ctrl+Alt+Del to get out and restart the game.
And by the way... I know you said that Beta 1 wouldn't be "FUN" and that you'd try to make it as unfun as possible in order to only get feedback on bugs... well I tried my best, but I must say, even in an early stage this game is lookin' good and already addicting even with the few elements in the game so far. Other than the bug I mentioned earlier, It's quite impressive. Nothing quite like sitting back, building my empire to a new golden age, only to see an enemy fleet coming in from Phase Space. My small fleet and a few defensive platforms were all that defended the border world to my empire, an ice planet I had spent thousands of credits on developing as a good colony. Luckily, my ships had far more skill than the others, a veterancy gained from a successful campaign to rid my corner of the galaxy from Pirates. After a heated battle and focusing all fire on the enemies flagship, I was able to take it down. The remaining fleet seemed in disarray after the loss of their command ship and tried to run, only to be stopped by my Phase Jump Disrupter and picked off my by frigates. Not even 30 seconds after my victory the enemy was begging for a truce. Wow guys... addicting already. Can't wait to see what the full game has in store.
