With sort column highlighting on when you sort by the first column the ansi escape char is chopped off instead of the leading space in the format string. This corupts the display. This problem was introduced upstream in v3.2.2 with the windowing feature. And it still persists without my little kludge patch on the url above.
Can you step by step describe your problem (after "top" start what do you press, ... etc.)? For me it seem right.
Start top from a linux console or xterm. Turn on 'z' color mode and 'x' highlight sort column. Move sort column '<' left until you are sorting on the first column. Bango!
Thanks. Now it seems like real and useful bug report:-) It will be fixed in FC4.
This bug was never fixed and still persists today. :-( And just for reference, my ancient patch http://www.GreenKey.net/~curtis/rpm/src/SPECPATCH/procps-3.2.3/top-col1sort.patch.html still appears to work.
Thanks. Fixed. Update to procps-3.2.7-8.2.fc6 or procps-3.2.7-10 (devel).
procps-3.2.7-8.2.fc6 has been pushed for fc6, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
