Description:
I notice a corrupt diplay with firefox 29 if I visit the google homepage : https://www.google.com If I click on the "apps" button ( top right on the screen ) I can see the google icons ( youtube, search, maps, drive, gmail ) but If I scroll some icons are missing, the display is corrupted ( missing icons ), I use KDE4, opengl 2.0 acceleration, radeon driver ( open source driver ), I have an ati radeon 4650 Pci express graphic card, you can see a screen capture for this bug ( see the attached file ), If I downgrade the firefox package ( 29.0-1 => 28.0-1 ) the bug is gone, so it's seems that something is wrong with firefox 29.0 Additional info: * package version(s) firefox-29.0-1, firefox-i18n-fr-29.0-1, * config and/or log files etc. Steps to reproduce: - install firefox 29.0-1 - go to google home page - click on "apps button" ( top right of the screen ) - then scroll the window where the google icons are displayed, after scrooling some icons are missing, it's a corrupt diplay after a downgrade to firefox 28 there is no corrupt display

this is strange, why this delay, this lag after a scrolling ?
with firefox 28 I don't have this strange behaviour
https://bugzilla.mozilla.org/show_bug.cgi?id=1004417
It doesn't seem to be related to the desktop environment or display driver in use.
I don't understand why firefox developers didn't manage to solve this bug, although Gijs has found the faulty commit who triggers the bug :
https://bugzilla.mozilla.org/show_bug.cgi?id=1004417#c4
worst: they have put the flag on "RESOLVED DUPLICATE " for the bugreport,
but the bug is still here, maybe they don't understand how to reproduce this bug ?
But yeah, there's not much more we can do besides filing that report and providing sufficient information.
Since the other bug is marked as fixed and the fix is specific to Mac OS X, I'll ask to reopen our report.
