All of these are relevant questions.

But a bug report is a responsibility of some _paid_ developers, so their
managers will be nagging the developers to resolve the issues.

I.e. the bug report will hopefully appear on somebody's "to do" list. And
it is good.

Actually, the release notes of gtk+ series should have included some
benchmarks on various OSes/with various backends.

I.e. the bug report should be files first, and the research should be
going after it.
