Britt, if "Force full screen redraw (buffer swap) on repaint" doesn't work then that confirms there is a problem with the driver. or hardware (probably driver). Because that option should give you flawless silky-smooth graphics so long as vsync or SwapBuffersWait support is enabled in the driver.

Also, your Xorg logs confirm that you already have SwapBuffersWait enabled by default:
[ 1524.476] (II) RADEON(0): SwapBuffers wait for vsync: enabled

So if "Force full screen redraw (buffer swap) on repaint" is also enabled then it's definitely a driver or hardware problem. Sorry :(

Other options you can try with the radeon driver are documented on the "radeon" manual page:
