My point exactly. If you report something like this on the Ubuntu bug tracker, your bug will be gathering dust forever. If you are (un)lucky some bug triager who has absolutely no knowledge of coding or the systems involved will ask you for logs that are useless to the problem at hand, and that will be it.
Every time someone says "[basic feature] does not work on Linux", someone else comes and says it's always worked fine for him. I'm not saying you are lying, but you are probably in a minority. I've also had problems with scaling on Linux and I gave up on it. Also, having two screens with different scaling was completely unsupported, unlike on Windows.
