Resizing a transparent window makes it disappear on macOS

[erf]

When i try to resize a kitty window with background_opacity 0.75 only the top bar is shown - the rest disappears. I'm on macOS using Kitty 0.12.1.

Works for me with macOS 10.13.6. Note that if you are ona beta of 10.14 there are problems with it, see #887

Strange. I'm also on 10.13.6 (17G65). I disabled the other options except background_opacity, but same result. Is there anything more i could try?

Here are some more stats:
MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
Intel Iris Plus Graphics 640 1536 MB

Oh sorry I think I know what you meant. While the resize is in progress the window is not drawn. Yeah that is a limitation of glfw+cocoa see glfw/glfw#1251 sadly I dont know of any way to fix it.

You'll notice the same thing with non-transparent windows as well, basically the contents of the window will not be drawn while the resize is in progress.

Ah ok. No problem. Yes i see that, but with an opaque background, you are able to see the black background whilst resizing ( so a little better ).
