i forgot to add that, when built with no-toolkit and without any alpha
or alpha-background spec, there's another new problem with exwm.  exwm
has a "system tray" where it puts applets like nm-applet.  before the
last changes to support alpha-background in non-gtk builds, exwm's
system tray had been working for me flawlessly.  now it doesn't work at
all (the icons don't show up in the tray area, and new, empty buffers
are created instead).  

when compiling with the lucid toolkit there's no such problem, and tray
icons in exwm still work well.

maybe this has nothing to do with alpha-background, but started at the
same time it was implemented for non-gtk toolkits.

thanks,
