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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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. Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Created attachment 814525 [details] Firefox screenshot Applications that use Xrender appear to substitute random characters of different fonts for characters that should be displayed. This affects at least Firefox, Thunderbird, gedit and fontforge. The attached screenshots in which the problem should be obvious were obtained with: rm -rf /tmp/ff mkdir /tmp/ff HOME=/tmp/ff /usr/bin/firefox & echo abcdefghijklmnopqrstuvwxyz > alpha.txt gedit alpha.txt & I am unsure how to debug this further; however, Firefox has a pref called gfx.xrender.enabled which when toggled to false completely fixes this problem. I don't know if there is a similar fix for gedit. The hardware is an Intel Core i5 CPU with "Ivybridge Desktop (GT1)" graphics using xorg-x11-drv-intel-2.21.12-2. It may be relevant that the AccelMethod for the Intel X11 driver is set to SNA because the default of UXA does not support Zaphod mode, which I use. So it's possible this is an Intel bug rather than an Xrender bug.
