Bug6.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0
Build ID: 20141126041045

Steps to reproduce:

With several tabs open (anywhere from 2 to 10, it doesn't make a difference), I clicked on another tab to switch to it. (I've also done the keyboard switch-tab shortcut.)


Actual results:

FF did NOT switch me to the tab I've clicked to (or keyboard short-cutted to).


Expected results:

FF should have switched tabs.
I have, say, 5 tabs open. As of the FF update (or upgrade? I don't recall) from about a month ago, when I click on another tab, the tab I've clicked on sometimes looks like it's having some kind of graphics issue. And FF doesn't switch to that tab. 

On one or two occasions, FF HAS switched to the other tab, but the image of the tab I was just in is seen in that new tab (this particular aspect of the bug I HAVE seen reported).

Can you still reproduce this if you disable all your add-ons? ( https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode )

No, it doesn't seem to happen in FF Safe Mode.

Since first reporting this, I've noticed that something has gone awry with Flash since the FF Upgrade, and this may be connected to that. 

I've had to remove and reinstall Flash twice and have found info to do a completely clean re-install of Flash, which I hope will resolve the issue.

Did this fix it? :-)

Nope! That had no effect. 

I think I'll have to roll back FF. 

The situation happens almost every time I switch tabs.

As you said it doesn't happen in safe mode, there's a good chance turning off hardware acceleration (tools > options > advanced (general subtab) > untick "Use hardware acceleration when available) will help.

If that does fix it, could you please go to "about:support" (Help > Troubleshooting information) and copy/paste the 'graphics' section here? There'll be some issue with Firefox in combination with your graphics card and/or driver that we need to look at (it may also be possible that updating your graphics driver would help).

Hey there.

Unless it's the upgraded FF that is not compatible w/the graphics card, I'm uncertain how that would be the issue. I've had this computer for 3 years. Everything else (display-wise) does seem to work OK. 

Hardware acceleration is always off btw.

Yes, that's what I was suggesting. :-)

It's very odd that this should be fixed in safe mode, but that hardware acceleration is already off in 'normal' mode... If you create a new Firefox profile ( https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles ) does that have the same issue if you're not installing all the add-ons that you've currently got installed?

(sorry for all the questions, just trying to pinpoint what is going on, as obviously we don't want it to happen but we do need to figure out *why* it's happening in order to fix it...)

Ah, no, I think I know what it is. Try going into about:config and disabling:

layers.offmainthreadcomposition.enabled

This is probably a duplicate of bug 1067470.
