Red Hat Bugzilla – Bug 446957
[nv] Fonts are blurred and unreadable, "monochrome" setting
Last modified: 2018-04-11 07:25:50 EDT
Description of problem: ----------------------- Fonts are blurred and unreadable when using specific applications. I first encountered the problem when attempting to use applications through Crossover Office 6.2. I assumed it was due to new components in Fedora 9 and was going to wait until the next release of Crossover. But after trying different font settings, I also found the problem in other applications. Steps to Reproduce: ------------------- 1. Use 'Appearance Preferences' in Gnome and select the 'Fonts' tab. 2. Select 'Monochrome'. 3. Open OpenOffice.org Writer. I've attached an image to this report.

To take some more ordinary application (OOo does some thing their own way) -- does it happen with gedit as well?
The problem only appears to affect OpenOffice.org and applications running through my installation of Crossover Office. Incidentally, the problem does not seem to occur in the version of wine in the Fedora 9 repositories. Perhaps this is a bug that only now affects OpenOffice.org and has been solved in recent versions of wine?
And what version of OOo is that exactly, rpm -q openoffice.org-core sounds a bit like bug 443735 Please give the output of "locale", the font listed as "Application Font" under gnome preferences and the output of "fc-match thatfont", e.g. "fc-match Sans", and your video driver e.g. grep "drivers" /var/log/Xorg.0.log
I had a look at bug 443735. That bug seems to refer to specific fonts and how they are displayed in the font selector. It occurs when font smoothing/hinting is turned on. My bug affects all fonts in the application when font smoothing/hinting is turned off. It also says that the bug was corrected when they installed a newer version of OOo. But the version that I'm running is even newer! My application font is Sans. Here is the output of the various commands you asked for: [mark@localhost ~]$ rpm -q openoffice.org-core openoffice.org-core-2.4.0-12.8.fc9.i386 [mark@localhost ~]$ locale LANG=en_GB.utf8 LC_CTYPE="en_GB.utf8" LC_NUMERIC="en_GB.utf8" LC_TIME="en_GB.utf8" LC_COLLATE="en_GB.utf8" LC_MONETARY="en_GB.utf8" LC_MESSAGES="en_GB.utf8" LC_PAPER="en_GB.utf8" LC_NAME="en_GB.utf8" LC_ADDRESS="en_GB.utf8" LC_TELEPHONE="en_GB.utf8" LC_MEASUREMENT="en_GB.utf8" LC_IDENTIFICATION="en_GB.utf8" LC_ALL= [mark@localhost ~]$ fc-match Sans DejaVuSans.ttf: "DejaVu Sans" "Book" [mark@localhost ~]$ grep "drivers" /var/log/Xorg.0.log (II) Loading /usr/lib/xorg/modules/drivers//nv_drv.so
*** Bug 447066 has been marked as a duplicate of this bug. ***
I see this weird-ass thing with the "monochrome" setting for fonts on a F-9 box with a nvidia and the "nv" driver at least. It goes away if I change the driver to "vesa" fwiw
Thinking this problem was specific to OpenOffice.Org I filed this bug report https://bugzilla.redhat.com/show_bug.cgi?id=447066
And it also goes away if Option "NoAccel" is used in /etc/X11/xorg.conf with nv, and I *dont* see this problem on the laptop with a i915 driver
(In reply to comment #9) > And it also goes away if Option "NoAccel" is used in /etc/X11/xorg.conf with nv, > and I *dont* see this problem on the laptop with a i915 driver Do you mean that component xorg-x11-drv-nv is more appropriate for this bug?
Well, its the only driver where I can reproduce it. Definitely not xorg-fonts anyway.
OK, let's make ajax happy.
Created attachment 308222 [details] simple standalone test-case Attached is a simple cairo test-case that reproduces it for me
Created attachment 308223 [details] and a little pic of how that looks on a nv driver
add behdad just in case the cairo guys are interested
Kind of a known driver bug IIRC. mclasen should know better.
Looks like it may be reproducable nvidia driver as well -- bug 449867 looks similar.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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
Moving to rawhide to hide from the autocloser.
Ben, give the testcase in comment #14 a shot when you get a chance. ISTR fixing something similar in XAA back in the day, would be nice to know if it's gone for good now.
