JFileChooser performance when using WebLaf

[4SFED]

I have noticed around a 10x increase in time to display a JFileChooser when using WebLaf. I came across this bug:

https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6372808

I took the same code there and adapted it to either use WebLaf or WindowsLAF, code attached.

FileChooser.txt

The results were as follows:

D:\Tools\FileChooser>java -jar FileChooser.jar false
start
Using WindowsLAF
leaving main.
Thread[AWT-EventQueue-0,6,main] :: Before new JFileChooser()
Thread[AWT-EventQueue-0,6,main] :: After new JFileChooser(), took [5632].
.showDialog exited.

D:\Tools\FileChooser>java -jar FileChooser.jar true
start
Using WebLAF
leaving main.
Thread[AWT-EventQueue-0,6,main] :: Before new JFileChooser()
Thread[AWT-EventQueue-0,6,main] :: After new JFileChooser(), took [61188].
.showDialog exited.

When using WindowsLAF it took 5632ms to open. When using WebLaf it took 61188ms to open.

I am using weblaf-complete-1.29.jar

Is this a known issue or am i doing something incorrectly?

EDIT: just tried with version 1.2.13 and the results are the same.

See #698, the underlying cause is the same from what I understand.
