Bug Description:
When launching the game, an error message pops up stating:
“Because a keyboard layout with an input method editor (Chinese, Japanese, or Korean) is installed in the system, ‘Exclusive Fullscreen’ mode is unavailable. ‘Fullscreen Windowed’ mode has been enabled instead. To unlock ‘Exclusive Fullscreen’ mode, please remove these keyboard layouts in Windows settings.”
This results in the game automatically forcing users with East Asian keyboard layouts into “Fullscreen Windowed” mode, preventing them from using “Exclusive Fullscreen”.
Why this is a Bug and Unfair (UX Issue):
Flawed Workaround: Instead of fixing the underlying engine issue where IME pop-ups or input conflicts cause crashes/lag in Exclusive Fullscreen, the developers have implemented a hardcoded lock. You are punishing a specific demographic of players for a technical limitation of the game engine. Other major games handle this seamlessly.
Unfair Barriers: Users are forced to either play in Windowed mode (which often introduces input latency, stuttering, and breaks features like G-Sync/FreeSync or HDR) or completely remove their native language keyboards from the OS. This is a massive, unfair barrier to entry for Chinese, Japanese, and Korean players.
