763277 - the new feature smooth scrolling in FF13 generates blur

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

User Agent: Mozilla/5.0 (Windows NT 6.0; rv:13.0) Gecko/20100101 Firefox/13.0
Build ID: 20120601045813

Steps to reproduce:

Steps to reproduce:

FF13 does enable by default smooth scrolling. smooth scrolling works fine, but...


Actual results:

the smooth scrolling generates blur! 


Expected results:

no blur during the scrolling! as in IE9 (IE9 with acceleration enabled!!, smooth scrolling enabled, on the same machine Vista32 sp2, without clear type).
this behaviour is due to firefox (I'd like to mantain the acceleration enabled!) , I guess, not to my machine/gpu drivers...because this annoying blur does appear even in a PDF text via firefox ( but the same pdf in the external reader looks fine: no blur during scrolling).

I hope that the smooth (vertical) scrolling in Firefox will work in the future without blur. Thanks.

PS: I dont want to disable the acceleration because I go jumpiness, better smooth scrolling with blur as jumpiness.

with ff18 the blur has been resolved. but it arised another issue.
scrolling at fast speed in ok.
smooth scrolling (one step with the mouse wheel)makes the reading of the moving text unpossible: the yexy lines do tremble.
only with ff18.
(acceleration should be enabled please).
thanks.
