Web animations (flash, gif, html) stop while moving the mouse


Hi!

I've been having a rather weird problem with web animations. I can't really remember when it started, maybe it was always like that on this computer (I bought it about 3 years ago). When I first noticed it, I asked about it around the internet, and no one had any idea what's going on, but back then I thought it only affects Flash, not all animations. I've recently noticed that it affects all web animations, not just Flash, so I thought I'd try again to look for some answers. Here's what happens, it's slightly different for different browsers:

- On Firefox, all web animations stop when I move the mouse. When I stop moving it, everything goes back to normal, as long as the mouse isn't moving (it happens with any mouse connected to the laptop, as well as with the laptop's touchpad)

- On Opera, gif and HTML animations work well, but Flash is just like on Firefox

- On Chromium, I've just noticed that everything's okay, but some time ago Flash animations always stopped while moving the mouse, just like on Firefox. Some recent Chromium update must have fixed it. I don't remember if other animations worked well then.

- On Chrome everything has always worked okay, that's why I've been using Chrome to play Flash games (I use Firefox for everything else)

I have an Acer Aspire 7540G laptop, with an ATI Mobility Radeon HD 5650 video card. I use the open source driver. I have Ubuntu with Gnome Shell, but the problem seem to happen no matter what distro and desktop environment I'm using. It even happens on virtualbox. :O I've searched in google, and it seems no one has ever had that problem. Does anyone have any ideas how to fix it? I know I could just use Chrome, but I'd rather use Firefox (I'm waiting for Chromium-based Opera, though. It should be awesome!)

Never heard of this one. This problem is usually designed out at a hardware level.

Taking a shot to nothing here, go grokking in the BIOS and see if you can set the interrupts as edge detect (It detects transition) instead of level detect (detects the low level). A mouse generates interrupts. This isn't the full solution, but it means usually that less processor time is spent on the interrupt.

Another shot to nothing is the boot option 'noapic' in the kernel command line. That drops higher interrupts, and you're back to 16. Let us know how you get on.

Thank you for the reply! I'll try doing that. I'll be away for a few days, so I'll try it when I'm back. One more thing I've just remembered, in the case when Flash animations stop when I'm moving the mouse, switching Flash to fullscreen seems to fix the problem.

Unfortunately, I can't do any of these things. There doesn't seem to be anything about interrupts in BIOS. And when I try booting with 'noapic' then the system doesn't even boot. It says things like this:

Disabling IRQ #11
Gave up waiting for root device
ALERT! /dev/disk/by-uuid/[some long number here] does not exist

The format of your kernel options should look like this:
Quote:
kernel somekernel root=/dev/something ro noapic
If a line like that causes it not to boot, it's weird, but you obviously need the extra interrupts in that case.

Next thing I would do is disable the flash, & java plugins one at a time, and browse around and see if either one solves it. If not, we come to video. Give much more precise information if you want an answer, as vague feedback is useless. Ubuntu what? what's the box/gpu/chipset? Is ram an issue (try the 'free' command)

If you have ubuintu, I think you can run
apt-get update

and get the latest versions of stuff. That might solve a strange issue.

I have had a similar issue some years ago. I don't remember what it was exactly that solved it, but I looked into the following:
-Desktop compositor
-ATI driver (I think the driver didn't have proper hardware accelleration enabled due to config problem)
-DRI
-Certain kernel parameters related to the graphics driver
-Played with XrandR


I think the reason it flickers or don't move when you move the mouse is that the graphics accelerator puts priority on the mouse and that for some reason there are not enough resources to keep running the other graphics.


Not sure though, but that is what was striking me immediately.

Hope it can get you further!

Dunno what this is, but, naww, it won't be "hardware interrupts." That's much too low-level. It'll be something having to do with X/XOrg screen repaints ... a mutex or something like that ...

If you move the mouse then pause briefly, do the animations resume instantly? Or is there a nearly-imperceptible delay?
