Well, the flickering tab problem is still with us, but in a somewhat different form. I did a cvs update of 21.2 around 4PM PST (2300GMT), October 18. Here's the test case for reproducing the problem: * Use these X resources (I don't know if these are really necessary to reproduce the bug, but I'm listing them anyway): Emacs*EmacsFrame.default.attributeBackground: black Emacs*EmacsFrame.default.attributeForeground: white Emacs*EmacsFrame.geometry: 177x55+6+20 Emacs*cursorColor: green Emacs.default.attributeFont: -*-Fixed-Medium-O-*-*-*-130-*-*-*-*-*-* * Use the attached .emacs file (called "bad.emacs" -- rename it to .emacs). * cd to XEmacs's src subdirectory, and run: ./xemacs * Use M-< to move the cursor to the beginning of the scratch buffer. At this point, the XEmacs windows looks like the attached "good.gif" (I resized the window to make the .gif file nice and small). * Do: C-x 3 # Split window vertically. At this point, the window looks like "bad.gif". Note the alignment of the right-hand window: the top of the text is cut off. Also note the top position of the right-hand window's vertical scroll bar. Based upon what's been discussed earlier, I suspect that this is a problem that's eventually causing some of the flickering. [ Hmmm. Looking some more at the gif file, there also seems to be a minor redisplay problem in the left-hand window. Look at the "intersection" where the horizontal and vertical scroll bars meet; there appears to be some "left-over text" from before the window split. ] * Do: C-x C-o # Move cursor to the other window. At this point, the window looks like "bad2.gif". Note that the bottom of the tab line has been totally erased. * Do: C-x C-o # Move cursor to the other window. At this point, the entire tab area has been erased, and is black. If you move the mouse into the tab area, the mouse cursor starts flickering badly. The truncated, top part of the text in the right-hand window is also flickering. I guess something is being continuously erased, or drawn and erased. (I've also attached a copy of my "Installation" file.) -- Darryl Okahata darrylo(a)sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
