Created attachment 856137 [details] Example of affected image Description of problem: With some specific jpeg images, eog will show an area of garbage instead of the expected image contents. This area will be of the size of the image, so the image is at least partly recognized as valid. The garbage will commonly be stripes and pieces of previously viewed images and of the current GUI. Version-Release number of selected component (if applicable): eog-3.10.2-1.fc20.x86_64 How reproducible: Always (with affected images) Steps to Reproduce: 1. Locate affected image 2. Attempt to view image 3. Actual results: Stripes of garbage displayed Expected results: Valid image displayed Additional info: Firefox is not affected by this bug and will properly display the same image file if opened as a file.

Still affected by the bug. I have checked that all images affected by the bug are images with a width of exactly 512, 1024, or 2048 pixels. Height of the image is irrelevant. This looks like something to do with a boundary condition on either a power of 2 or a multiple of 512 pixels. Zooming in or out of the image has no effect on fixing or triggering the bug.
A further data point. This bug seems somewhat related to the display driver. The two affected machines are both x86_64 installations with xorg-x11-drv-intel-2.21.15-7.fc20.x86_64 . However, the bug does not occur with a x86_64 laptop (HP Pavillion dv4) that uses a radeon chipset, and also does not occur on an Acer Aspire One that runs a 32-bit installatin of xorg-x11-drv-intel. Additionally, this bug seems to be known upstream: https://bugzilla.gnome.org/show_bug.cgi?id=723577 https://bugzilla.gnome.org/show_bug.cgi?id=656224 https://bugzilla.gnome.org/show_bug.cgi?id=711325 http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=587c4866652e40e1e228b333028114766a6d3b08 I confirm that I am using SNA as intel backend. Will test with default backend (UXA?).
I can confirm that using the default UXA backend for the intel driver instead of SNA works around the eog image corruption issue. This is really an intel driver bug.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. 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 20 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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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.
