M13ProgressHUD appearing from top left corner when shown from UITableViewController

[HaikuOezu]

I have created a fairly standard setup for an app; a UINavigationController (no custom class) with a UITableViewController as its root controller, displaying a list of items fetched from a server and I want to show a HUD to show the progress.

This is the code I'm using; it is taken straight from the sample app

- (void)viewDidLoad
{
    [super viewDidLoad];

    HUD = [[M13ProgressHUD alloc] initWithProgressView:[[M13ProgressViewRing alloc] init]];
    HUD.progressViewSize = CGSizeMake(60.0, 60.0);
    UIWindow *window = ((LPAppDelegate *)[UIApplication sharedApplication].delegate).window;
    [window addSubview:HUD];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [HUD show: YES];
}

The HUD works but instead of "popping" from the middle of the screen it "grows" from the top left angle of the screen to its full size.

I looked allover the sample project to find differences and the only thing I'm doing different aside from performing this on viewDidAppear is that I'm calling this from a UITableViewController.
I tried moving this to a UIViewController and it works perfectly (even with said ViewController being part of a navigation stack) so it seems it is the table view controller's fault

Any idea why this is happening? I found that editing M13ProgressHUD.m's layoutHUD and moving

    backgroundView.frame = CGRectIntegral(backgroundRect);
    _progressView.frame = CGRectIntegral(progressRect);

outside the UIView animateWithDuration block fixes the issue, but it doesn't look ideal and since it only happens inside the UITableView there must be something else causing it.

Please take a look at the animationPoint property of the HUD. Let me know if setting that works for you.

I did try setting the animationPoint to CGPointMake([UIScreen mainScreen].bounds.width/2, [UIScreen mainScreen].bounds.height/2) and while the HUD does appear from the middle of the screen the "origin" point of the scale animation is still its top left corner.

I know that UITableView does some weird things, Like the lines between the table rows are drawn above the self.view of the UITableViewController. I'll create an example and see if I can fix it.
