fonts getting crazy in GTK applications under KDE

[Laurent Claessens]

I've installed my quantal via deboostrap (I've no other ways) and I've made all upgrades. (apt-get update/dist-upgrade)

I'm using some GTK apps under KDE (kdm) : thunderbird, gvim and the windows decorator (because of compiz).

When I open my cession (KDE+Compiz), everything is ok.

After a while, the fonts are getting crazy (see the attached screenshot of gvim). It seems to be GTK-related since the problem arises in gvim, thunderbird, synaptic and the windows title, but not in Konqueror or in konsole.

I'm not sure what triggers the problem since when I open the cession, the fonts are correct for some minutes or even sometimes hours.

I think that this bug is related to the nouveau driver or to my Nvidia card : my laptop (that has the same installation but has an Intel graphical card) has no problems.

For information :

$ lspci | grep VGA
18:01:00.0 VGA compatible controller: NVIDIA Corporation G86 [GeForce 8300 GS] (rev a1)

Other constatation : Firefox and Thunderbird are clearly triggering the bug.

When gvim is the only opened GTK app, I've hardly no problems. When on the other hand I open Firefox or Thunderbird, things are rapidely degenerating.

My Nvidia card died last week. I am thus using the default Intel card included on the mother board (same installation, same hardware apart of the Nvidia) and I've no more any problems.

So
1. this is closely related to the Nvidia card.
2. I'm no more able to give further details for helping the debug process.

As far as I am concerned you can close this bug (while I guess this is not really solved)

Maybe it is related to bug 568492
