So, I know the Debug mode is not really supported, but the Alt + 1, 2, 3 and 4 screenshot feature that makes huge screenshots was working for me before.
But now it does this (part of big screenshot X3):
As you can see UI is rendered normal, but everything else is jigsawed, you can still tell what you look at from zoomed out version. The jig saw gets worse the bigger the screenshot is.
The feature was awesome, it would be amazing if it makes into the game without debug mode.
How it was before (WARNING! HUGE screenshot):
Take Alt + 1-4 screenshot with debug on.
