Re: Contiguous redisplay of the menu and beeps

[Richard Stallman]

    (2) A bug in redisplay.  Somewhere Qinhibit_point_motion_hooks doesn't
    get bound to Qt but so far I was not able to find out where.  There's
    evidence that the bug shows up when `column-number-mode' is enabled,
    `current-column' is called and triggers sgml's point-entered hook.

If you can arrange to enter GDB (perhaps with a breakpoint at Fsignal)
and send the backtrace, we should be able to figure out straightaway
where that is.

Thanks for getting a handle on this problem.
