Hello everyone,
There has been an issue for the past few months where some users would have the game in a very small window (instead of their native screen resolution). This was pointed out by in our forums and we were able to fix it a day or two ago.
The issue was missed for so long because it did not appear on our test machine after we upgraded the version of Unity we were using for the game (the upgrade was to match the Xbox version). There seems to be a regression in the version we used which caused this issue.
Since the test machine didn't have any issues, we pushed the update thinking everything was fine. We apologize for letting this issue persist for so long as fixing it ended up being simple but it took a bit of time to figure out a good way to do so (and we were simply unaware of it for so long).
Please let us know if anyone else still experiences any issues with the screen scaling.
