I'm kinda writing on behalf of LOVE2D (http://love2d.org), requesting that you guys make it possible for window transparency (where you make the window transparrent and stuff, unless you code there to be objects in the window). If you guys want to see the bug report on love2d's website, its here(please do it anyway): https://bitbucket.org/rude/love/issue/1049/background-transparency

We probably won't do exactly what you describe (because it can't be done on most platforms anyhow), but basic window transparency is waiting to be merged into SDL:

But that's literally the entire window being alpha blended, not the window minus parts of your rendering.

Hello, and sorry if you're getting dozens of copies of this message by email.

We are closing out bugs that appear to be abandoned in some form. This can happen for lots of reasons: we couldn't reproduce it, conversation faded out, the bug was noted as fixed in a comment but we forgot to mark it resolved, the report is good but the fix is impractical, we fixed it a long time ago without realizing there was an associated report, etc.

Individually, any of these bugs might have a better resolution (such as WONTFIX or WORKSFORME or INVALID) but we've added a new resolution of ABANDONED to make this easily searchable and make it clear that it's not necessarily unreasonable to revive a given bug report.

So if this bug is still a going concern and you feel it should still be open: please feel free to reopen it! But unless you respond, we'd like to consider these bugs closed, as many of them are several years old and overwhelming our ability to prioritize recent issues.

(please note that hundred of bug reports were sorted through here, so we apologize for any human error. Just reopen the bug in that case!)

Thanks,
