I have four monitors connected to my PC, with my main screen in the middle. Almost always when the game crashes, and occasionally when it exits cleanly, starting the game again will open the Launcher correctly, but place the full screen game off to the lower right. If I exit the game and try again it tends to fix itself. and open full screen on the main monitor. Next time it happens I'll double check, but it might be aligning the lower right corner of the game window according to the lower right of the wrong monitor. I noticed in 1.06, and it is still present in 1.08. With 1.08 I noticed that the new, expanded Character equip screen tends to be misaligned with regards to the mouse. I might hover over the armor, but get text for the helmet. Clicking seems to select equipment under the cursor, but the text is wrong. Only the vertical alignment is wrong.
My bad. The startup mains screen (not the launcher) still occasionally shows up at the wrong place on the monitor.
