User-Agent:       Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.0b13pre) Gecko/20110226 Firefox/4.0b13pre
Build Identifier: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.0b13pre) Gecko/20110226 Firefox/4.0b13pre

all tabs have notches on left top & right top, nav bar has thin black bars on or near buttons, left part of first letter of some words has extra thickness when not bold, searchbar search button has similar black corruption on lower left of icon, add-on bar has black corruption on many icons, first letter of text on some websites has extra thickness or corruption. when hovering over links/buttons on google.com, hover image has many small black triangles along the side edges of the buttons, as well as on some buttons i am not hovering on. other websites display the same small black triangles along the left & right edges of buttons, with or without being hovered on. all purely cosmetic, but quite ugly & annoying.

Reproducible: Always



Expected Results:  
no display corruption

i suspect this may have been caused by a windows update because about the same time an update was installed yesterday was when i first noticed the issue occurring, but for some reason i cannot uninstall the update which i believe may have caused it (KB947821).

i know this is not caused by my display drivers (which i completely uninstalled, cleaned, & reinstalled, trying to fix the problem, as the same drivers showed no such corruption before this began occurring) or the latest build of minefield (4.0b13pre) because i tried older versions & got the same results. this issue does not occur in any other browser or program on my computer, only minefield.

apologies, this was NOT caused by a windows update, but by minefield update b12 & persisted with b13. i've reverted to b11 & the issue has resolved itself.
