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

Subject: Performance Regression in 21 - CSS
Hi everyone,
I've noticed that some parts of one of my applications is significantly slo=
wer 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 dow=
n 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/3fa02ee96a6dadbc20cacbf399=
a2d65df708eee1
According to the description and the discussion in the PR - this wasn't sup=
posed to change any performance.
Is this regression known?
Otherwise, I should create a ticket for it.
Greetings Florian
