Comment 1 Valdis Kletnieks 2006-03-23 19:47:06 UTC 
I've confirmed this is a NVidia driver issue.  Using the Fedora Core 5
xorg-x11-server-Xorg-1.0.1-9.i386.rpm, things work fine.  However, once the
Fedora Rawhide xorg-x11-server-Xorg-1.0.99.1-1.i386.rpm is installed,
the open-source nv driver works, but the NVidia 8178 drivers have the issue.

I'm guessing some subtle API change is giving 8178 indigestion.

As another data point - the missing characters aren't lost entirely - quite
often, moving the cursor over them to force the widget to focus and redraw
causes the text to appear (although it may spontaneously re-poof out a few
seconds later).

(System is a Dell Latitude C840, Linus 2.6.16 kernel, FC5 Rawhide userspace,
GeForce 440 card).

This problem still happens in nvidia-1.0-8756.

And xorg-x11-server-Xorg version is 1.0.99.2-2.

AA is off or using bitmap font and font with sbit, this problem happens.
Comment 5 Aaron Plattner 2006-04-10 17:52:56 UTC 
You're right, the change to the glyph ABI is responsible for this breakage.  We
hope to support the new driver ABI (version 1.0) in a future release.

This should be fixed in the 1.0-8774 driver which was released yesterday.
