I tried to bisect it, but that went nowhere.. too many changes between
3.19..4.0 to identify backportable fixes just by looking at it.

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.

Hi,
I am having similar issues; when I suspend my laptop, the UI doesn't
render properly anymore.
My specs are:
Dell Latitude E5450

I'm running Debian 8 Jessie.
Anything I can help with? I can paste info regarding my system if
needed.
Thanks,

Hello,
I think I'm experiencing similar issues, although a lot more

only sometimes, and they are quire minor

What does your xrandr give? I get that the maximum is 32767 or something,
although my resolution is not that. Is that normal?
Perhaps the resolution changes after suspend? My xrandr is the same before and
after I just checked, but the maximum value I find a little strange.

The funny thing is that it used to work properly up to some update.
David, did you found the way to downgrade to that previous version? I
read somewhere that it is not a very safe stuff, because something can
became unstable, but in any case have you already tried it?

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.

the UXA fix never worked for me by the way. who is working on this bug?
Does it look relatively easy to fix? Are there version that have worked
in the past and if yes, could they be temporarily implemented for this
version of ubuntu?

It affects me too. This happens after resuming a suspend. In FVWM, the
bug renders my screen incomprehensible and is quite reproducible.
See image attached.

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
the common thread which links to my observations about google-chrome
above.

This bug is affecting me too. I can confirm that the SNA approach is
working as a workaround, but as said before, performance is heavily
impacted.

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
issues in this bug.
Any of the gurus fancy taking a crack at it?

David, I can confirm the above workaround "fixes" the issue for me,
however, it's hardly an alternative since rendering performance takes a
huge hit, some of my applications are hardly usable and even terminals
