Bug#640464: xterm: rendering problems (pixels not erased?)

After doing tests on another machine, this is not related to the
libx11* packages (in some cases, the problem doesn't occur, and it
might be the case here). I'm not even sure that this is a regression,
but in such a case, I don't know why I didn't notice it before. For
the moment, I've tried to downgrade packages as shown in attachment
(downgrade1), and the bug still occurs (after a reboot).
To reproduce the bug, I've attached a file "text", obtained from
xterm logging (md5sum: e522fe4b2a4e45e39761550e8a5426f7). The steps
are the following:
1. Type: xterm -geometry 80x60 -e 'sleep 10; cat text; sleep 999'
2. Put a smaller window covering the middle of the right part of
the xterm window.
3. Wait for the text (from "cat text").
In case this is due to the driver, I use the nouveau driver (both
machines have a NVIDIA card).

[1mcurl[m is a tool to transfer data from or to a server, using one of the[m
supported protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP,[m

curl offers a busload of useful tricks like proxy support, user authen-[m

curl is powered by libcurl for all transfer-related features. See[m

[1mURL[m[m
The URL syntax is protocol-dependent. You'll find a detailed descrip-[m
tion in RFC 3986.[m
[m
You can specify multiple URLs or parts of URLs by writing part sets[m
within braces as in:[m
[m
http://site.{one,two,three}.com[m
[m
or you can get sequences of alphanumeric series by using [] as in:[m
[m
ftp://ftp.numericals.com/file[1-100].txt[m
ftp://ftp.numericals.com/file[001-100].txt (with leading zeros)[m
ftp://ftp.letters.com/file[a-z].txt[m
[m
Nested sequences are not supported, but you can use several ones next[m
to each other:[m
[m
http://any.org/archive[1996-1999]/vol[1-4]/part{a,b,c}.html[m
[m
You can specify any amount of URLs on the command line. They will be[m
fetched in a sequential manner in the specified order.[m

If you specify URL without protocol:// prefix, curl will attempt to[m
guess what protocol you might want. It will then default to HTTP but[m
try other protocols based on often-used host name prefixes. For exam-[m

Curl will attempt to re-use connections for multiple file transfers, so[m
that getting many files from the same server will not do multiple con-[m
