Javascript mode extremely sluggish?

Post by syam44 »

Hi,

Since the Java applet is hardly usable for me now (see my other post) I tried the Javascript mode, which turns out to be extremely sluggish on my computer.
Whenever I place a stone the CPU usage goes up unreasonably (one core at 100% for something between half a second and a full second), and simply moving the mouse around also shows a worrying lack of responsiveness.

I realize the Javascript mode is intended to replace the old Java applet, which is a good thing per se, but not if the responsiveness is as terrible as I am experiencing. :(
Am I the only one having such issues?

Using Firefox 7.

As a follow-up, the problem disappears when I disable so-called compositing display (Debian/KDE4) so it seems it's a video driver issue on my side.
Sorry for the false alarm, even though it's a bit surprising that goproblems.com is the only website that exhibits such behaviour.
If I'm not mistaken (I think I saw this somewhere on the forum) you're heavily using HTML5 Canvas, right?

it's using SVG, which is a bit different from Canvas, i think
