Incorrect sizing of windows
I tried building Geany with the latest version of gtk-osx and there seems to be some issue with the latest GTK version where the window isn't sized properly (I'm still using macOS 12). Here's a screenshot:
The title bar is several pixels off and the bottom of the window is cut off. When resizing, the title bar is resized at a different speed than the rest of the window - eventually the window becomes aligned with the title bar but when resizing further, the title bar jumps again so it's several pixels off again. When moving the cursor to the border of the window to resize, the resizing cursor appears at the position of the title bar, not the border of the window itself. Looks like some rounding/modulo problem somewhere in the code.
I can provide the binary if needed.
