Bug#585494: xterm 258 has broken scrollbar, doesn't follow new output at random
Package: xterm
Version: 258-1
Severity: normal
When going from xterm255 to 258, the following happens:
At random, at xterms on the X11 servers stop having working
scrollbars. In that wedged state the xterm scrollbar will stay, the
text shown will stay where it is and new output will be consed up
below. You can manually scroll down but it will then again not
display new text.
Then, at random, it snaps into working behavior. This is a fresh
install that doesn't have much running in the X11 server, just chrome,
fvwm2, chat and pidgin. I have obserserved going into and out of
wedged state literally without using any of the other clients.
Again, whatever happens here, it affects all running xterm258s at
once. It is X11 server wide.
When wedged, all xterm-258s are weded, no other xterms. 258s that are
on a remote tty (but local display) are wedged as much as long 258s.
Other versions of xterm, including 255, continue working normally,
including older xterms on local tty.
It is probably coincidence but should be mentioned that getting in and
out of the wedged state might be related to using mutt (a tty
mailer). But I have been unable to reproduce the bug by deliberately
messing with mutt.
Again, this doesn't happen on just one machine. I had another
debian-testing that I started a remote xterm on (remote tty, local X11
server) and that worked when that xterm was 255. I upgraded to 258
and it broke the same way the first 258 is broken.
