User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release) Build ID: 20130803192641 Steps to reproduce: 1. Install Firefox 23.0 on Ubuntu and Ubuntu derivatives. 2. Scroll vertically, either direction. Actual results: Body text -- standard 16pt text and smaller -- turns blue while the display is being scrolled. Text returns to black instantly when scrolling stops. Disabling "Smooth Scrolling" corrects this. Toggling "Hardware Acceleration" has no impact. Hardware: ThinkPad W530 with Nvidia K1000M 2-gig video and onboard Intel. Problem persists when BIOS is set for discrete card, Optimus, or Nvidia-only with Nvidia driver. Expected results: Text should not turn blue when the page is scrolled.
Thanks for taking the time to report this! Could you attach a screenshot of the problem? Does the problem happen if you start Firefox in Safe Mode? See http://support.mozilla.com/en-US/kb/Safe+Mode
The text needs to be moving, so no screenshot. Yes, it persists in Safe Mode with smooth scrolling enabled.
Component: Untriaged → Graphics: Text
Product: Firefox → Core
Do you also reproduce this with a clean profile: http://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles ? After you update your Flash and GPU driver, the problem still persists?
I'll try a clean profile when I have time to figure out how to save and restore my current profile. However, the blue text appears on first use of Firefox on a newly installed system. I've checked. In Fedora 19, as well. Flash is 11,2,202,297. The graphics driver is whatever is current in Ubuntu 13.04 w/18.104.22.168. (On Fedora, it was also present using an Nvidia driver. I haven't intalled Nvidia on Ubuntu here.)
jonc, Do you still see this when using a current version?
