Windows DPI handling and Physical vs Logical Size

[markusmoenig]

Hi

See the issue here on winit: rust-windowing/winit#4414

Its not a bug per se, just an issue which cannot be handled correctly without special cases on the user side when using a softbuffer / winit combo with the current API.

I thought I would just point this out :)

Thanks

Actually kchibisov in the above thread has a point. softbuffer on the Mac should provide the logical size and let Mac OS do the upscaling (which is more or less for free on the GPU).

This is most likely a duplicate of #177 / #22. There have long been discussions and ideas to decouple (physical) buffer size from (logical) window size, but nothing materialized yet.

Right, all I am saying is that currently it is not possible to create a functional cross platform, working application (instead of a small demo with rectangles) without having user side platform defines.

Pixels is unsupported. Softbuffer is half baked without any development going on. Sigh.

Feel free to contribute your use-case and expertise if you think development is stalling. A good starting point might be #269.

I would wish to contribute more to softbuffer, but for me (on Android) the problems start 4 dependencies deep and changing softbuffer is futile until those are resolved first.
