Links flicker in FF3 after switching tabs in Kubuntu jaunty

[naught101]

Binary package hint: firefox

After switching tabs in FF3 links flicker between hover and normal styles. It doesn't usually matter, because clicking the link still works, BUT if the hover style does something important, like opening a sub-menu (like javascript nice-menus), then the sub-menus will also flicker and usually be unusable.

If the page has just loaded, either after clicking a link, or reloading, this doesn't happen, and everything works as normal.

This may not be a firefox bug, but rather something to do with the KDE/GTK crossover - I'm getting similar problems with inkscape when trying to move objects with the mouse.

Basically, if the mouse moves, then inkscape seems to register that it's moved, but once it's stopped moving, it goes back to the starting position. If the mouse moves smoothly, it the object flickers between the original position, and the new position.

I see this in FF3 in jaunty/gnome, very annoying...

I see that behavious too. The behaviour looks a little familiar with an old bug with Xorg/XFree that would occur if you added a mouse twice... And it looks like that's what is going on:

The laptop has a 'GlidePoint' and I'm using an external mouse with usb received (logitech), but it adds 4 pointers, the usb receiver twice, the glide, and a ps/2 mouse. I only have one keyboard too, so I don't think it's right that it adds those twice...

End result: mouse/keyboard events are received multiple times (and at not exactly the same moment), and xorg starts doing weird things.

Perhaps this is what is hitting everybody with this bug, and #312353, and #310020, etc...

I don't think that's the problem. Mine looks like this, but I've
hibernated twice, so it's re-enabled the microsoft USB mouse twice:

$ grep "Adding input" /var/log/Xorg.0.log

I guess that the ps/2 mouse is the joybutton in the middle of my
keyboard. All three mice give the same response.

I don't know why the video bus is there twice - perhaps because I have a
d-bus video out?

Also, my xorg.conf has no pointer devices what so ever, just my video
device, monitor and screen.
