【BUG】tabview background image

After I add a background image to each tabview, swiping the screen becomes laggy.On my device (allwinner f103), switching tabview refresh is very slow

Is it slow with LV_OPA_COVER too?

I’ll test it now

There seems to be some improvement, but it’s not as smooth as before when I didn’t set the background image, please ask me what I need to lv_obj_clear_flags/style?
