I'm using the version of X current for Debian Jessie.
I find that windows are sometimes corrupted. The typical case
is in XTerm, when the bottom line is covered by a copy of the
second-last line. It happens a little more than half the
time, so some sort of race condition.
It is not confined to XTerm; Emacs and Aisleriot show some
of the same behavior.
In all cases, moving the window will cure the problem. The
redraw is correct.
So my conclusion is it's a fault in X. I've never had to
report an X bug before.
If you will give me a list of info to provide, I will send
it in a later message.
Otherwise, thanks for your attention.
