@HendriXXX I’m curious about the crashes, in general all QTWebEngine browsers crash pretty frequently on Haiku, is that something you are seeing there too? It somehow has to do with the Javascript interpreter, but was never easy to debug the issue.
I think you can easily reproduce if you use Falkon for an hour or so, it will surely crash a few times.
Does it have to do with the single-core VS multi-core topic you mentioned?
