Triple-monitor setup screens not lining up

I'm running Loki on a Dell Studio 9550 with three monitors in total, all on a 1920x1080 resolution. Whenever I start up the computer, the monitors do not appear to line up properly. The leftmost 3 pixel columns of the middle screen are repeated on the rightmost side of the left screen. There also appears to be a gap of about 5 pixels between the middle screen and the right screen; I can move stuff 3 pixels to the right from the edge of the screen before it starts appearing on the right screen.
Opening arandr and rearranging the monitors there fixes it, until I reboot or use the Displays control panel to rearrange the monitors there.

Running xrandr gives me the following geometries:
eDP1 connected 1920x1080+3+0 (normal left inverted right x axis y axis) 350mm x 190mm
HDMI1 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 530mm x 300mm
DP2 connected 1920x1080+3845+0 (normal left inverted right x axis y axis) 530mm x 300mm

If you look at the x offsets you'll see that eDP1 is offset by 3 pixels, overlapping HDMI1, and that there is a 5 pixel gap between HDMI1 and DP2
