Hi all,

I'M running thunderbird-24.6.0-1.fc20.x86_64. Sometimes (rather often,
but not always) having problems with threads in thunderbird: After
opening a thread, all opened sublines are unvisible, until I move the
mouse pointer over them (without click): then they will appear.

This happens both with ati and nvidia video cards.

Anybody has this effect too?

Kind regards

Nope, everything is absolutely visible - nouveau.

Having running nouveau too (nvidia gforce 210), but sometimes invisible.

OK, to see whether the issue is related to Xorg nouveau video module for NVIDIA 
graphics chipsets i.e. 'nouveau_drv.so', temporarily you can replace it with 
the Xorg basic modesetting fallback video module i.e. 'modesetting_drv.so'.

# yum install xorg-x11-drv-modesetting

Create a file "/etc/X11/xorg.conf.d/00-modesetting.conf"
with the following four lines:
Section "Device"
       Identifier "video0"
       Driver     "modesetting"
EndSection

After that restart X, or simply reboot. :)
Everything is visible?

Seems to help, thank you. Kernel issue?

I'd picked this
https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=xorg-x11-drv-nouveau

But before that, take a look at
https://apps.fedoraproject.org/packages/xorg-x11-drv-nouveau/bugs/all

Hi Poma,

I will check these 2 URL's, but as I told already in the first mail of
this thread, this is possibly an issue for the radeon driver too
(SAPPHIRE HD 5450).

Kind regards

What Desktop Environment is in use?
This is probably related with graphics acceleration.
