What I find even more interesting is that I've pretty much given up on
Chromium (the only program, let alone browser, which is showing
painfully slow response on my system) and switched back to iceweasel...

Do movies/videos play OK from a movie player?
Does iceweasel exhibit the same behaviour on the same URLs?

Do you have a dedicated graphics card or are you using graphics on the
motherboard?  If using a dedicated graphics card, check that any
graphics on the motherboard is turned off.

Check you driver settings.  Do you have acceleration turned on, etc?

Got 3D enabled like for gaming, etc?

Try turning off one of the monitors or better configure your system for
one monitor, and see if the problem persists.

This doesn't happen with any other browser?  And only with Chrome when
its display is full-screen?  What plugins/extensions do you have
installed in Chrome?

Do you have any torrents or file sharing software running?

Slow Display of Graphics in Chrome

[Alan Chandler]

Just recently, I notice a sudden slowing down of the display of areas of 
the screen in Chrome when it fully maximised ( but still with toolbar 
etc on display)


I am running a dual monitor gnome 3 setup with intel display driver.

Quite frequently, but not predictably so (say once every few minutes) 
Chrome, when displaying a web page whilst fully maximized gets very slow 
and displays blocks of the screen but then hangs for a few seconds 
before continuing with some more and hanging again.


You can stop it doing this by dragging the toolbar down from the fully 
maximized position.  I don't think I have seen it when not fully maximized.


Anyone else experiencing the same?

Not here.  Just as fast maximized (1920x1080) or less than max'd which
is the norm for me. But I'm not using Gnome, only a window manager
Openbox on Wheezy 64-bit.

How much RAM on your graphic card?  How much total system RAM?

This information seems harder to find than ever.  lscpi says I have 
either 4M (non prefetchable) or 256M (prefetchable) memory, but its an 
Intel driver which takes from main memory, of which I have 16G


I tried looking in /var/log/Xorg.0.log, but that hasn't been touched 
since before I got the new monitors.  My guess is gnome is using wayland 
(from the various switches I can see in htop)


I don't think its the display directly, I only experience the issue in 
Chrome

If you want a Chrome-like browser, what's wrong with Chromium? Is it lacking in
some way which necessitates the use of Chrome?

Although I don't use Chrome or Chromium anymore, I experience this with
*Iceweasel*, of all web browsers. In my experience Chromium has always been a
lot more responsive and snappier- so I experience and associate exactly
this problem with the Firefox-based browsers; Abrowser, Iceweasel, IceCat, etc.

Strange.

Does anyone else experience these strange hangs with the Firefoxes?

For me they are almost identical to the problem Alan has with Chrome.
