it seems they are all indeed glowing (confirmed both by instrumenting the code 
as well as looking really closely at the screen during animations :) but the 
visual difference between hovered and not-hovered for the SVG based items is 
very, very small.

it seems the code in Plasma::IconWidget is working as expected, as is the 
Plasma::PaintUtils::transition .. 

the applets which paint themselves (battery, e.g.) don't have a hover effect 
and that's unfortunate. something to be improved on (making the hover effect 
easier to implement in custom applets like that).

but for the other items, this could perhaps be due to a change in the artwork 
which renders the highlight effect almost useless.

in fact, i just went into the icon settings control panel and noticed that the 
highlight effect for icons was set to Gamma with value 0. changing that to have 
the highest possible value makes the change on the icons more visible.

then i changed it to colorize the icons .. and again it was more visible but 
interestingly enough, due to the small amount of colour used in the default 
system tray icons, only small bits of the icons were affected.

one way to confirm that this is indeed the issue would be to switch icon themes 
to one that uses colourful icons for the system tray. if the effect becomes 
visible again then that is the problem. given my research just now into the 
problem, this looks likely.

can you confirm?
