1073986 - Firefox randomly highlights bits of a page in black

Status: RESOLVED DUPLICATE of bug 1074024

(Firefox :: Untriaged, defect)

Description

[Phil]

Attachment: firefox_bug_3.jpg

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20140923222114

Steps to reproduce:

Used Firefox as normal. This issue only presented itself in the last few days. Issue persists even after a full uninstall/delete and reinstall


Actual results:

Firefox has been highlighting random bits of a page with black, making it difficult or even impossible to read. On Wikipedia, it highlights some of the textboxes as I'm typing, meaning I cannot see what I am typing. On Facebook, random sections of the page are blacked out as I scroll (they change as I scroll around the page). In the Addons section of Firefox it highlights the background of the available addons when I search.


Expected results:

Firefox should not be highlighting these things.

I got the same issue after updating to FF 33b7.
The "black boxes" appears to me also in the tab area, Google Maps and while scrolling areas inside the page (like the cc list in this page).
FYI
Adapter 	ATI Radeon HD 2400 Series
Driver Version	8.892.0.0 (Catalyst 11.9)

The issue disappears disabling HW acceleration.
