(In reply to Vasco Rodrigues from comment #5) > Can confirm this, from a new installation of fedora 22, also does this. After updating packages, seems fixed.
Please check if it exists somewhere else than in the browser, firefox never handled well font updates, it usually needs a restart to clear such effects
(In reply to Nicolas Mailhot from comment #8) > Please check if it exists somewhere else than in the browser, firefox never > handled well font updates, it usually needs a restart to clear such effects I can't test right now because I downgraded. Would it be ok to test in LibreOffice after upgrading again?
I don't remember if LibreOffice shares the same bug. windows-originated apps tend to suck at handling font updates (because on windows, you do not update fonts and when you do you need rebooting anyway) GNOME used to be the gold standard, since behdad fixed most warts there, so I'd test in gedit (I hope no one configures away font setup there)
I cannot reproduce the issue with gedit or Firefox on fedora 22. However, it's still present in the fedora 21 package. (Sorry for the wait, I had to get hold of the other machine with fedora 22.)
prolly some kind of fontconfig cache problem ?
Given that it is the cache problem, does fc-cache -f help? if not, I don't think it is. FWIW does this issue only happens after updating packages? or does it keep to be presented after restart apps or desktop even?
Ok, I updated the package again on fedora 21... the bug displays itself after some seconds on Firefox, e.g. with DejaVu Sans. With DejaVu Sans Bold another funny one is that "€" is displayed as "Rs". fc-cache -f doesn't help. I'll try not to downgrade before next reboot to tell you how a restart affects the bug...
After reboot things are better, but not quite right. I still see occasional random glyphs displayed for all sorts of digrams with "f" (and perhaps others), in a seemingly different font too. The difference now is that if I select the text then the display glitch is corrected.
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '21'. 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 21 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.
Is this bug still exist in F23? Is not please close else move to F23. We don't want to loose any valuable bug :)
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.
