Description of problem: When scrolling down a page in Firefox, it fails to redraw intermittently. This leads to a tearing effect. Version-Release number of selected component (if applicable): 4.0.1 How reproducible: frequent Steps to Reproduce: 1. Choose random website 2. Scroll up and down the page Actual results: Section close to the top of the window fails to redraw. Screen tears. Expected results: Should be tear-free. Additional info: If I try to take a screenshot, the window is redrawn and the tear disappears. I am using an nvidia 6600GT with the binary driver.
I should also mention I haven't seen this behaviour in other programs such as nautilus. The behaviour is specific to firefox.
I see this with nVidia GeForce 6150SE nForce 430, using akmod-nvidia from Rpmfusion. Haven't tested with nouveau yet. Smolt URL: http://www.smolts.org/client/show/pub_bed58531-672c-4452-b3ee-392a3ff73a2d
Thanks for the report. We are sorry that we cannot help you with your problem, but we are not able to support probems realted to binary-only drivers. If you would be able to reproduce this issue using only open source software, please, reopen this bug with the additional information, but in meantime I have no choice than to close this bug as CANTFIX (because we really cannot fix it). The open source 'nouveau' driver (in package xorg-x11-drv-nouveau) is the recommended alternative for users of Nvidia graphic chips. It is used by default in Fedora 11 and later if you remove any customizations that explicitly set the video driver. The older "nv" driver may be needed in some cases. It is also available in older Fedora releases. Install the packages xorg-x11-drv-nouveau or xorg-x11-drv-nv and override the X server's default choice if necessary. See https://fedoraproject.org/wiki/Features/NouveauAsDefault for more information. If you used a non-packaged version of the driver from the Nvidia website please clean your system from additional libraries and software it installed. For users who are experiencing problems installing, configuring, or using the unsupported 3rd party proprietary "nvidia" video driver, Nvidia provides indirect customer support via an online web based support forum. Nvidia monitors these web forums for commonly reported problems and passes them on to Nvidia engineers for investigation. Once they've isolated a particular problem, it is often fixed in a future video driver update. The NVNews Nvidia Linux driver forum is located at: http://www.nvnews.net/vbulletin/forumdisplay.php?s=&forumid=14 Once you have reported this issue in the Nvidia web forums, others who may have experienced the particular problem may be able to assist. If there is a real bug occuring, Nvidia will be able to determine this, and will likely resolve the issue in a future driver update for the operating system releases that they officially support. While we does not support the proprietary nvidia driver, users requiring technical support may also find the various X.Org, XFree86, and Red Hat/Fedora mailing lists helpful in finding assistance: X.Org mailing lists: http://www.freedesktop.org/XOrg/XorgMailingLists XFree86 mailing lists: http://www.xfree86.org/sos/lists.html Red Hat/Fedora mailing lists: https://listman.redhat.com/mailman/listinfo

Please try to disable HW acceleration (Edit -> Preferences -> General and the "Browsing" section). Also try to disable smooth scrolling.
No combination of HW acceleration and smooth scrolling has any visible effect (it doesn't make the tearing less or more visible). I did restart FF after setting the options every time.
I can reproduce it on F19: $ rpm -q firefox xorg-x11-drv-intel xorg-x11-server-Xorg kernel kde-workspace firefox-25.0-3.fc19.x86_64 xorg-x11-drv-intel-2.21.12-2.fc19.x86_64 xorg-x11-server-Xorg-1.14.3-2.fc19.x86_64 kernel-3.11.6-200.fc19.x86_64 kde-workspace-4.11.2-1.fc19.x86_64 I've tried composed desktop both with XRender and OpenGL with forced VSync.
This issue is still present in Fedora 20 release.
I can confirm it with nVidia GTS450 and Nouveau on Fedora 20, when running off LiveCD.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This issue is still present in Fedora 21 release.
This issue is present in Fedora 22 and KDE 5.

Please see comment 12
I can't reproduce it with Fedora 22 using: firefox-41.0.2-2.fc22.x86_64 xorg-x11-drv-intel-2.99.917-15.20150729.fc22.x86_64 xorg-x11-server-Xorg-1.17.2-2.fc22.2.x86_64 kernel-4.2.3-200.fc22.x86_64 plasma-workspace-5.4.2-4.fc22.x86_64 The rendering backend used is OpenGL 2.0, with GLX OpenGL interface Vsync is set to automatic. Firefox is not set to do smooth scrolling, but is set to use hardware acceleration. I'm using the same hardware as I mentioned in Comment #4
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
