If less than 1%. The dynamic format change should not happen when the resolution does not change and when only the framerate changes but very slightly, i.e. from 50000/1677=29.81 to 89/3=29.66 so a "percentage change" of less than 1% (i.e. 100*(29.81-29.66)/29.66 = 0.50 < 1 ). In that case just ignore it to avoid unnecessary renegotiation. https://bugzilla.gnome.org/show_bug.cgi?id=759043
