Hi Daniel, Here are the results:
> 1. Enable both: > Workarounds > "Force full screen redraws (buffer swap) on repaint" > OpenGL > "Sync To VBlank" (it should be enabled already) Result: WebGL Aquarium runs (i.e., desktop doesn't lock up), but at ~2 FPS > 2. Disable both: > Workarounds > "Force full screen redraws (buffer swap) on repaint" > OpenGL > "Sync To VBlank" Result: if the window is covering most of the screen when launching the app, the WebGL aquarium or any other WebGL app doesn't start the first time. Looks to me like the browser's rendering loop is running out of control, consuming all CPU and preventing the HTTP resources from being downloaded correctly. The desktop doesn't become completely unresponsive; it's still possible to close the browser window. After reloading the aquarium once, it loads; Chrome's GPU process (which is running the OpenGL code) is running at 100% CPU, and the aquarium redraws once every ten seconds or so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/988079 Title: [nvidia] Dismal compiz performance on HP Z600 with 30" landscape monitor To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/988079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
