Some sizes of various fonts in various applications have blank spots
in glyphs.

Version-Release number of selected component (if applicable):

mesa-*-7.11.2-1.fc16

How reproducible:

Always

Steps to Reproduce:

2. Change font sizes between smaller and bigger sizes.
3. Observe artifacts in glyphs.

Some font sizes (the common ones) have artifacts, blank spots.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log*; check with grep Backtrace /var/log/Xorg* which logs might be the most interesting ones, send us at least Xorg.0.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.
