User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

Set Zoom Text Only. 

Go to a bugzilla bug page. It has "transition-property: all" for comments

Zoom with Ctrl +



Actual results:

The zoom is done using the transition. On FF28 this is done rather badly.
It's not so bad on FF32.



Expected results:

Without Zoom Text Only the page just jumps to the new zoom value which is much better.
Component: Untriaged → Panning and Zooming
Product: Firefox → Core
This sort of zooming is handled by the layout code synchronously. The CSS component is a better fit.
Component: Panning and Zooming → CSS Parsing and Computation
It has been like this for quite a while. BTW I don't see a difference between Fx28 and Fx32.

Some pages on which the zoom text only zoom behavior is horrible since nearly everything on the page is animated:
