Lutris games issue in gaming mode

games added through lutris, when opened in steam gaming mode and switching away from the game (pressing the home button and switching to the library, for example) while its opening, the game seems to open on top of the steam ui making it unusable (i can still hear steam ui sounds), same happens when switching to another game while one opens, it opens as a tab in that games window.
is there a fix or something ive done wrong?
