Hi, Since this morning (and the most recent upgrade apparently) I am experiencing serious display issues when scrolling with my mouse up or down on any website: the whole text and other page components appears to shift left or right and becomes so blurry that it is completely unreadable. The same issue is encountered on all websites visited Operating system: Windows XP professional version 2002 - SP3 Firefox Version: 26.0 Screenshot of the issue: http://i43.tinypic.com/2r3vz81.jpg I have tried to: -create a new Boolean called "layout.paint_rects_separately" (without the quotes) and set it to true -Setting gfx.content.azure.enabled;false -Setting gfx.direct2d.disabled;true -Disabling all add-ons None of these did change anything to my issue. Any suggestion on how to fix that is welcome.
