UI glitch when setting [floaty setButtonImage:theNewImage]; iPhone X iPhone XR iPhone XS

[gustavengvallthomascook]

Im using Objective c and after initialization of Floaty I want to change buttonImage via FloatyDelegate like this:

- (void)floatyWillOpen:(Floaty *)floaty
{
    [floaty setButtonImage:[UIImage imageNamed:kCloseMeny]];
}

- (void)floatyWillClose:(Floaty *)floaty
{
    [floaty setButtonImage:[UIImage imageNamed:kOpenMeny]];
}

For some reason Every other call seems to add 34 pixel to position. If Im writing out frame in console I get:

If Im doing the same on iPhone 8 or devices with "regular" screen (physical home screen and no face recognition) Im not experiencing this issue. Here is same console log for iPhone 8:

This is my setup method:

- (void)setupExpandingMenu
{
__weak typeof(self) weakSelf = self;
    Floaty *floatyMenu = [Floaty new];
    [floatyMenu setButtonImage:[UIImage imageNamed:kOpenMeny]];
    floatyMenu.rotationDegrees = 0;
    floatyMenu.overlayColor = [UIColor.blackColor colorWithAlphaComponent:kMenuAlpha];
    floatyMenu.fabDelegate = self;
    
    FloatyItem *gotoNewVersionItem = [[FloatyItem alloc] init];
    gotoNewVersionItem.title = @"GO TO NEW VERSION";
    gotoNewVersionItem.titleLabel.font = [CAPPTextStyle textHeadingThomasBold].font;
    gotoNewVersionItem.titleLabel.textAlignment = NSTextAlignmentRight;
    gotoNewVersionItem.icon = [UIImage imageNamed:kSneakPeekGotoTripView];
    gotoNewVersionItem.handler = ^(FloatyItem * item) {
        // tap action
    };
    
    [floatyMenu addItemWithItem:gotoNewVersionItem];
    
    [self.view addSubview:floatyMenu];
}
