Wahoo!! The vivid-proposed kernel seems to fix the issues for me too.
Thanks to all who worked on this: Much appreciated.
Just out of interest, is it any clearer yet what the problem was?
Thanks again.

I am not aware that anyone is working on it. I suspect that if it's a
driver issue then it would require the xorg people to fix it, not
xubuntu.

Is there any way to revert the xorg driver to an old version that does
work?

Interesting. I tried openbox and the bug is there with that window
manager.
Does gnome-shell use hardware acceleration? If so, then that might be

I noticed there was an update to the intel driver earlier this week for
my xubuntu system. It fixed one other problem I'd been having (slightly
buggy playback of video in VLC) but doesn't seem to have helped the

In case it's worth anything, the following may help to diagnose the

When I resume from suspend and lose desktop icons, panel icons, and
random bits of text, I find that starting google chrome (or even just

I have managed to find some sort of work-around for this. It turns out the

I am also experiencing this kind of issue. For me, the problems manifest as
buggy display of video when VLC is in windowed mode. (Fullscreen mode is fine.)
Also, when I suspend my laptop, the display is partially corrupted when I
resume. See here:
I found that it was sufficient to install only the texlive-lang-cjk

Public bug reported:
Waking from suspend, everything seems normal, except the graphical

moving the mouse over icons can cause them to be redrawn, sometimes not.
