flickering in JSVGCanvas
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
hello everybody!
im using a JSVGCanvas embedded inside a SWT Container. the jsvgcanvas
state is set to ALWAYS_DYNAMIC since i update some svg components via
dom to move them around in the picture. when i move them fast (input via
mouselisteners), im getting bad flickering in the svgcanvs around the
moved object, also sometimes the update just stops and the picture
update seems to hang. im using jdk 1.6.01 and 1.5.11.
enabling double buffering does not help at all, the result is unchanged.
what else could i do to improve the performance?
thanks,
marc doerflinger

I've known people who have had similar issues in Java2D and manually
implemented an additional buffer (triple buffering) to solve the
problem.

Stop using SWT? Since this never happens with Swing/AWT I suspect it's
an issue with how SWT supports Swing. Unfortunately I don't know anything
about SWT so I can't help much.
