That might not be easy to reproduce even before #208, anyway, e.g., being dependent on a particular build, etc. It's ok to close it though... -- Thomas E.

I revisited valgrind last night, and noticed that one of the references to uninitialized memory was in that area (I recall seeing that one earlier and noticing that it was a bug in Xt). Adding a memset in fontutils.c made that one go away (in #208). That may be what Burrows is seeing. -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net

In that case, I need more information regarding the color change. I can't do much about the dot-sizes unless I build up a bitmap (which is doable, but rather high cost for a single character). -- Thomas E.

I took another look at this one today, and it seems that you're getting the same picture as I would expect if line-drawing is done from built-in tables, e.g,. because the font does not support it. That's done with a stipple, which seems to come only in a finer set of dots than the fonts were done in. ACS_CKBOARD was a detail that I added in 2004/07/05 (xterm 192). The color issue appears to be fixed in a change I made in 2005/04/18 (which is part of #202).

Given that you had problems with recent xterm, could you please give a try to the experimental xterm_204-0pre1 package that in 5 hours will pass from incoming.debian.org to the archive?

Package: xterm Version: 6.8.2.dfsg.1-7 Severity: normal Since the last xterm update, I've noticed that some graphics characters are occasionally displayed in a garbled fashion. The one I usually notice is ACS_CKBOARD; the symptom is that instead of being painted as a pattern of alternating white and black dots, it's painted as some sort of solid color. The corruption goes away if I redraw the characters (for instance, by selecting them with the mouse or exposing the window surface). It may be related that some test code which prints Chinese characters has been misbehaving since around then, and that all of these misbehaviors appear to be limited to a Unicode environment -- when I reset the locale to en_US, the problem with ACS_CKBOARD goes away (obviously I can't test the Chinese characters in en_US, though :) ). I've posted an example of the corruption I'm seeing at http://people.debian.org/~dburrows/broken-scrollbar.png. I manually cleared a few characters of the scrollbar so you can see how it should look. To reproduce this, start an xterm in a UTF8 locale, then run stock aptitude from unstable; that screen is what shows up for me.
