            Bug ID: 30523
           Summary: [gdb/tui] Exiting tui doesn't clear prompt line
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tui
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

Say we enter gdb, and type "foo" (indicating cursor with ^):
...
(gdb) foo
         ^
...

Then we enter tui using C-x 1, and we have:
...
(gdb) 
      ^
...

After typing "tui disable" or C-x a to leave the TUI mode, and we have:
...
(gdb) foo
      ^
...

The "foo" string is not part of the readline buffer, if we do ^L it's gone.

It probably shouldn't be there in the first place after exiting TUI.

--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
Doesn't reproduce with TERM=ansi or TERM=ansi-for-tui.

Probably related to ^[[?1049l and ^[[?1049h, switching between normal and
alternate screen buffer.
