The new borderless fullscreen mode does not work, it's functionally the same as fullscreen except the window does not capture your cursor. When alt tabbing you are still blackscreened breifly just like when tabbing out of fullacreen mode.
borderless mode does not work
I dont see what other information i could possibly give, borderless mode behaves exactly like fullscreen except it does not capture the cursor to the window, ergo- it does not work. everyone in my guild except one or two people have the same exact issue. I suspect those two people and you do not understand how borderless window is supposed to work. I should be able to seamlessly tab in and out of the game as if its in a window, but it behaves exactly the same as fullscreen instead.
no, i am indeed able to seamlessly tab in and out, it is not like fullscreen. it works exactly as borderless fullscreen is supposed to and as it does in other games. your issue is not universal
if most people in your guild have the problem then there's probably a pattern though. maybe it's an issue with knightlauncher?
i'm not seeing this behavior, it works as expected for me. you'll probably need to give more information
