List scrolling is very slow in JavaFX 17

[Glavo]

Hi,

I'm one of the maintainers of the open source project HMCL (Hello!
Minecraft Launcher*)*. This is a Minecraft launcher based on JavaFX.

In the past year, we have received a lot of feedback on performance
problems. Through performance analysis, I noticed that from JavaFX 17 ea+8,
the performance of list scrolling is terrible.

I analyzed the method calls and noticed that the updateItem method of
ListCell is called 8 times more frequently in JavaFX 17 than in JavaFX 16.

I guess this is due to the following commit:


https://github.com/openjdk/jfx/commit/8e547571fb3d40df843c27fc11921b5d4765c481

I wonder if this is a bug?

Best regards,
Glavo
