First, I love Upscayl. Just used it to make about a decade of early lower resolution digital family photos 90s and early 00s printable and beautiful on HDPI screens. It's fantastic software.

> Not developing on and doing little testing on Windows sure sounds like the problem to me.

Most open source developers are not going to switch to "developing on" Windows because of posts like this. Nor should they. Upscayl is on GitHub and would probably appreciate some testing and fixing on Windows.

As a developer, I don't use Windows at all. When I make cross platform software, dealing with MS-DOS anachronisms isn't interesting or fun. For paid work, yeah, OK I'll do it. But for free stuff, I can see where a developer might not want to put a lot of effort there and focus on the interesting part of their project.

That's perfectly fine so long as one doesn't claim to be cross-platform (or supports Windows).

but it is cross-platform and supports Windows.

There might be Windows specific bugs but those are fixed as soon as the community gives feedback.
