I have managed to find some sort of work-around for this. It turns out the problem is in the xorg intel driver, not pm-utils. Switching the 2D accelleration mode from "SNA" to "UXA" as detailed here:
https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues
and here:

removes the problems with resume from suspend.

However, it does substantially impair the performance of my laptop,
especially when I run a virtual machine with Windows as the guest OS. I
have to do this quite a lot, so I guess I have to choose the lesser of
two evils.

This is not really satisfactory, so if there is anything else that
anyone can suggest, I would love the hint.

Title:
  Faulty behavior when resuming from suspend

Status in pm-utils package in Ubuntu:
  New

Bug description:
  Waking from suspend, everything seems normal, except the graphical
  elements and text on my desktop are not drawn properly. Sometimes,
  moving the mouse over icons can cause them to be redrawn, sometimes
  not. It appears not to matter how I initiate the suspend (e.g. by
  closing laptop lid, or by calling pm-suspend explicitly) and it
  appears not to matter whether I am using an external display or the
  laptop's own screen.

  All other hardware appears to be working, and I can restart the laptop
  by clicking where the icons ought to be. The only symptom seems to be
  that the drawing does not happen correctly.

  I'm not sure what additional information I should provide to help
  diagnose the problem, so please advise me.

  Also, if this is more likely to be a xfce issue, then please change
  the package on the bug report.
