Resizing an nedit window under the above configuration produces a broken display.
1) Run a VNC server on Linux (I'm using Fedora Core 2)
2) Inside VNC, run GNOME's window manager "metacity". (The easiest way to do this is to put "exec gnome-session" into your .vnc/xstartup file before starting the server.)
3) Start up a VNC client.
4) Open nedit on any 2 files with signficant text, in tabbed mode.
5) Grab the right edge of the windowand drag left so that it chops off the text. Without letting go, drag slowly to the the right.
See attached screenshot for problem.
Metacity insists on using opaque-resize; if you have wireframe resize you will not see the problem. Also, everything's OK if you only have one tab. KDE's window manager seems okay under both VNC and non-VNC.
