(In reply to sasamotikomi from comment #14)

I have not seen any such problems using the radeon drivers. I have seen
glitches in the form of horizontal lines across the screen with the intel
drivers and many users report similar problems on Linux as well regardless =
of
the acceleration method. Note that there is zero overlap, intel uses UXA and
SNA whereas others use EXA, Glamor, and/or none. I believe this is the first
that I've heard of a font rendering issue, all the other reports of artifac=
ts
are lines or boxes over the image. It does sound more like it would a probl=
em
with font rendering code than drivers since you say it occurs on both intel=
 and
radeon.

Can you give steps to reliably reproduce the problem?
