Fullscreen size changed event bug?


I have problem on OSX (10.14.6 but I think 10.15 have the same issue). When the app is in fullscreen mode (SDL_WINDOW_FULLSCREEN_DESKTOP) and resolution is increased (by moving app to another monitor or by changing screen size in system setting) no event about window resizing is trigerred (SDL_WINDOWEVENT_RESIZED nor SDL_WINDOWEVENT_SIZE_CHANGED). And the app is drawn with black strips on sides.
Is there a way how to find out that resolution was changed? Or is it a bug in SDL?
I’m using version 2.0.10
