Hi Everyone, Sorry for the delay - but I couldn’t find the time to extract the TestApplication for this bug. Luckily, I found another application, which is also open source, which is affected by the application.
I'm speaking about https://www.jfx-central.com/ - both the desktop and web versions are affected. I’ve seen a performance deterioration of 10x when switching pages when using JavaFX21 compared to JavaFX20. I’ve created a ticket with further instructions on how to test it: https://bugs.openjdk.org/browse/JDK-8322795 Greetings Florian Kirmaier On Fri, 27 Oct 2023 at 21:31, Andy Goryachev <andy.goryac...@oracle.com> wrote: > Please create a ticket, Florian.
