onSystemUiVisibilityChange listener not called after rotation as should

Question

im pulling my hair on this. What I want to do is system ui + my views toggling with total fullscreen (statusbar and navbar hidden + immersive_sticky)

-- By default I want the ui to be hidden, i.e. just content showing. This seems to be a ridiculous problem

On first activity onCreate everything seems to work. After I rotate and call hide again, onSystemUiVisibilityChange does not get called even though mDecorView.getSystemUiVisibility() and argument flags being set dont match.... As if system cached the last value somewhere and then because its the same, does not trigger the listener .. sounds reasonable, right? so I call syncChrome manually with last visibility value from bundle. Now UI is hidden or shown after rotation corretly. HOWEVER, now if I toggle it, system bars come back as should, but the listener is not called!!!! If I toggle it one more time, everything goes away as should, and if I toggle it one more time, it fixes it self and works (both system ui and my ui is shown correctly)... so basically after 3 toggles it starts to work as expected -____-

One idea was to not change the system visibility after rotation, just sync chrome .. nope, if I ommit setting the HIDE_FLAGS, then system bars are shown .. so it doesnt remember the last values as it did in the case above...

Am I doing something wrong or is this a bug?

(I could not care about the system ui listener and manually show / hide my ui manually, however there is a glitch, when hide() is called in onCreate, and then I toggle to show the system ui, the navbar and status bar both have weirdly transparent background, even though theyre supposed to have color -- if I toggle it off and on again then navbar / statusbar color comes back as should)

...Banging my head so hard...
