cannot resize Glade 3.38.1 application window on MacOS
I'm using the brew-installed version 3.38.1 of Glade on Mac OS Catalina 10.15.6.
As it stands I cannot resize the Glade application window at all, the only thing I can do is to click the maximize and minimize buttons on the top right.
When I move the mouse cursor to a corner or edge of the window, the mouse cursor changes to the 'resize' cursor, as expected. However, it appears that the areas when that happens lie just outside the application window, so that when I click for dragging the window border for resizing, the OS thinks I'm clicking on the window below and moves Glade into the background. For me it looks like that the 'active' areas that are defined around the window lie just outside the window edges, and not above them which would be required so that button presses for resizing fall into the window's own coordinates, and not outside.
See the attached video on how this looks in practice. At first you'll see me finding the spot on the window edge where the arrow cursor is turning into the resize cursor. It's already visible that the spot appears to be outside of the window frame. After that I try to click on that spot, which makes the window disappear (because the OS sees me clicking on the window below). The rest of the video shows me trying this for all four edges and a corner, all with the same result.
This only happens for the main application window, dialogs opened by the application like Preferences or the Toobar Editor don't seem to be affected (even though their 'active resize area' lies just outside the window like in the main window)
From a UX perspective this is utterly frustrating and makes Glade pretty much unusable for me right now. I'm only wondering if I'm the only person having this issue, given on how disruptive it is I had expected to find a bug report about it already.
