After creating a 500x500 pixel image and displaying it:

```julia
using ImageView
imshow(rand(500, 500))

```

I found out that the `hoverinfo` is wrong by ~50 pixels regardless of the size of the displayed image (the cursor was at the bottom-right corner of the image before this screenshot):

Is anyone else getting the same results?

Here’s for a 100x100 image (cursor was at bottom-right corner):

**Interestingly** , for a 50x50 image it gets it right (couldn’t get the cursor _exactly_ on the edge):

What is going on…?

Works for me. Maybe report as a bug to ImageView and give full platform details & version info of packages (at least Gtk, Cairo, Reactive, GtkReactive, and ImageView).

Thank you Tim! [Issued](https://github.com/JuliaImages/ImageView.jl/issues/148). Let me know if anything is missing etc.

Did I want to pin GtkReactive? I guess I did at some point. Anyways, I freed it and now all is well in the world. Thanks goes to his holiness @tim.holy…
