Hello,
I just tested this with our JavaFX application and can confirm that
there are massive differences. It takes around 1-2 seconds to completely
apply all application stylesheets in JavaFX 20 but takes around 6-7
seconds in JavaFX 21.

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

Please create a ticket, Florian. Would it be possible to profile
the application when scrolling?
Thank you

Hi everyone,
I've noticed that some parts of one of my applications is
significantly slower with 21. It's fast with 20.
The application heavily uses (and reuses) TextFlow with a Cell
pattern.
When I scroll, it is smooth with 20, but has big freezes with 21.
I've tried all the commits that happened in between, and
pin-pointed it down to the following:
ticket: https://bugs.openjdk.org/browse/JDK-8304959
PR: https://github.com/openjdk/jfx/pull/1070
commit:
https://github.com/openjdk/jfx21u/commit/3fa02ee96a6dadbc20cacbf399a2d65df708eee1
According to the description and the discussion in the PR - this
wasn't supposed to change any performance.
Is this regression known?
Otherwise, I should create a ticket for it.
Greetings Florian
