Title Alt+Tab causes the game to exit fullscreen mode

Launcher Type Twitch Desktop App

Modpack Infinity Evolved

Details of the issue I've been playing IE:E recently and for some unknown reason my games runs way smoother (60fps) in fullscreen mode than in windowed mode (40fps), but every time I Alt+Tab out of the game it exits fullscreen mode and returns to windowed mode, this gets annoying after some time.

However I do remember that there are modpacks that allows me to Alt+Tab out of the game without exiting fullscreen mode, so I went to check if there's any mod in the modpack that makes me able to do so, but I didn't find anything peculiar. I also checked vanilla Minecraft and found out that I could Alt+Tab out the game without exiting fullscreen mode.

What's probably causing this problem?
