I can see this issue arising every now and then after the boot up. I'll
investigate in more detail and provide info on when it actually happens
and what processes are running.
'Toolbars' are the things controlled by the Window Manager -> Style ->
Theme :). Correct wording would probably be window decorations as you
put it.

This was on the same machine that 4.4 release was running up to now, and
with that release I had no problem in logging in in ~5 - 7  seconds. I
think this might also be connected to the fact that several xfdesktop
processes are spawned when I try to log in.

Looking at the USE flag in /etc/make.conf I see that jpeg is enabled
system wide. I have not changed the flags before emerging Xfce 4.6.1,
but I'll recompile the gtk+ anyways.
For gtk+ in particular I have following flags already enabled/disabled:

USE="cups jpeg -debug -doc -jpeg2k -test -tiff -vim-syntax -xinerama"

Hmm, maybe I should enable 'jpeg2k' flag also, that is currently disabled?
[-    ] jpeg2k - Support for JPEG 2000, a wavelet-based image
compression format

Thanks!

Best regards,
Hinko
