Sorry, I can't reproduce the bug, I tried several times, caught the bug
only once with *UXA disabled*, so I guess it's unrelated to UXA. What's
interesting is in one case I noticed slight glyph corruption to just a
few charactors and they are automatically corrected after a while.

Contents of /etc/X11/xorg.conf:

I will send in X log when catch the bug again.
