Huge JavaFX performance drop in Debian Jessie

[Markus KARG]

Chris,

can you please check what the JFX thread does whilst the scroll-freeze (e.
g. using jstack or jvisualvm)? It would be great to learn whether it is
related to JDK-8145565.

Subject: Huge JavaFX performance drop in Debian Jessie

Upgraded my netbook (Intel GMA3150 onboard graphics) from Debian Wheezy to
Debian Jessie and JavaFX performance has suffered a huge drop :(

Possibly not JavaFX related but native apps (firefox etc) all seem to
perform the same and glxgears runs full sync framerate and 350fps unsynced.

JavaFX stages open blank and can take 5 seconds to render. Trying to scroll
a scrollbar pegs the CPU (java process at 100%) and hangs the app for 10s+.

Previously stages opened in under 1s and scrolling was instant.

My DemoFX test platform (Canvas based effects) seems to run the same so it
only appears to be windows / stages that are affected.

It's an old (2010) system but JavaFX performance has dropped from slow to
unusable.

Will keep investigating and test on my Debian desktop once I upgrade it to
Jessie.

Cheers,

Chris
