I have a 1080p monitor and use a custom 4k resolution (not DSR) for Super Sample Anti Aliasing purposes in various games. In Grim Dawn the game will extend beyond the edges of my display when trying this resolution in the Boderless (Windowed) mode. The game is correctly scaled to the display in Fullscreen Exclusive mode.
Some other games like Slay the Spire and Monster Hunter World correctly handle my method of Super Sampling in Borderless display mode.
