display goobers in 21.5-b11, 21.4.12

Hi, If "xemacs -vanilla" (21.5-b11 or 21.4.12) is run with the following X resources set: XEmacs.default.attributeForeground: white XEmacs.default.attributeBackground: midnightblue You see all sorts of display cruft along the outer edges of the frame. Random grey lines appear frequently when listing completions and aborting out of completion listing commands. For example, C-x C-f <space> results in a grey line drawn along the bottommost pixel or two of the frame (under the minibuffer). If I then do: C-g I'm left with a short vertical grey bar along the left edge of the frame where the modeline was for the split window when showing completions. This is not completely deterministic, sometimes everything is fine, other times the vertical bar extends along the whole extent of what was the upper window. If I load a file (C-x C-f) and then kill the buffer (C-x k <RET>) then the entire left edge of the frame has a two pixel wide vertical grey line. C-l clears it. I can send screenshots if anyone is interested. The bug does not appear in 21.4.6 (as distributed with RH 7.3). The problems show whether or not the buffers-tab is on or off, though I suspect has something to do with that code or the code supporting it. thanks, Greg
