I have set $Platform::backgroundSleepTime to 1,this fps is 59,but some window is in the rect of the game window,the fps down to 33.

What do you mean? It is a feature that the game uses less resources if the program is in the background, so naturally the FPS drop as well. I would not recommend to disable that feature.

@Duion I mean when the program is in the background, but it is show. If there is no window in rect of it. The fps do not drop.If there is a window in rect in it,the fps drop.
