thank you, I didn't think about the callback definition, that solves my problem :)

And to my surprise, the rest of code actually handles the ERROR_OUT_OF_DATE_KHR panic, the window doesn't crash on a resize event anymore (maximize / unmaximize / minize using the window buttons).

But I see there is another bug, when I drag the window border to apply a manual resize (or double click the window title), I get error Failed to unfocus input context: XError { description: "BadDrawable (invalid Pixmap or Window parameter)", error_code: 9, request_code: 149, minor_code: 4 }.

• it's hard for me to say whether or not it should be solved in The example panics with ERROR_OUT_OF_DATE_KHR on a window resize. #103 or another issue should be created?
• note that I'm new to the GPU world, so I can't really say as what the problem could be 🤷

@jirislav Thank you for your PR! I think you need to rebase your changes with the latest main to get CI to pass.

Also just a warning that if #109 merges first, this will presumably have lots of conflicts

Thanks for the heads up. I think I'm going to wait for it to merge and then redo my work on wgpu sample 🙂

@jirislav #109 is in, I'll be happy to review and merge this when you get a chance to rebase or rewrite it on top of that :)

I believe this has been done by #299, but thanks for your work here!
