nope, no custom configs in retroarch. even deleted the config folder in retroarch just in case but still, the problem persists. Btw, i meant to say that i am using bigbox, not launchbox. Is there such a button map option as "toggle fullscreen" for bigbox? i dont see one.
retroarch minimizes only when i use bigbox controller automation to change the volume, so i tried switching hotkeys in bigbox but the problem is still there.
checked launchbox button maps just in case, and toggle fullscreen is set to none.
