Created attachment 407372 [details] Screenshot showing video distortion Description of problem: Minor Video distortion in gstreamer-properties test window when the test window is resized and another windows is placed on top of the test window. (See attached screenshot) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Run gstreamer-properties, go to the Video tab, and set the Default Output Plugin to X Window System (X11/XShm/Xv) 2. Hit the Test button 3. Resize the test window, then place another windows on top of the test window. Actual results: Distortion of the video in the test window (video data is shifted slightly to the left for the area left of the foreground window) Expected results: No video corruption Additional info: ATI Technologies Inc RS690M [Radeon X1200 Series] [1002:791f]
Does it works properly with vesa driver ?
Enabled the vesa driver by adding the following to /etc/xorg.conf.d/00-evdev.conf Section "Device" Identifier "Videocard0" Driver "vesa" EndSection Using the vesa driver, the test (as described at https://fedoraproject.org/wiki/QA:Testcase_radeon_xvideo) was unsuccessful, showing the following error: "Error running pipeline 'X Window System (X11/XShm/Xv)': Could not initialise Xv output [xvimagesink.c(1416): gst_xvimagesink_get_xv_support (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink1: No port available]" Testing with the option "X Window System (No Xv)" does not show the video distortion issue, but the same is true when using the Radeon driver. Other observations of note are: 1. The video distortion is across the entire test window; not just to the right of the foreground window as originally (mis-)stated. 2. The position of the foreground window influences the severity of the distortion. 3. There is also a slight (1 or 2 pixel) vertical distortion that occurs depending on the position of the foreground window. This is noticable when moving the forground window as the lower boxes will shrink/grow as the window is moved vertically. 4. The severity of the distortion is dependent on the width of the test window. Increasing the width of that window increases severity of the distortion. 5. Moving the foreground window away from the test window (so they no longer overlap) causes the test video the be displayed correctly. 6. Running this same test with compiz enabled shows none of these problems. The test video is displayed correctly.
I can confirm Jeff's observations. I didn't notice the distortion during the Test Day, because it's so subtle. My system is a Toshiba Satellite Pro A210 with the same graphics chip as Jeff's: ATI Technologies Inc RS690M [Radeon X1200 Series] [1002:791f]

This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. 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 WONTFIX if it remains open with a Fedora 'version' of '13'. 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 prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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. Thank you for reporting this bug and we are sorry it could not be fixed.
