            Bug ID: 30526
           Summary: [gdb/tui, TERM=3Dansi] Exiting tui doesn't clear screen
           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 run TUI with TERM=3Dansi in an xterm:
...
TERM=3Dansi gdb -q -tui -iex "set tui border-kind ascii"
...
and press ^L to fix the slightly broken screen.

Now, type "echo \n" and press enter until the prompt is at the bottom of the
screen.

Now type tui disable<enter>.

The only thing that changed in the screen is that the cursor moved to the s=
tart
of tui disable.  We have in fact left TUI, which we can see by doing ^L whi=
ch
will clear the entire screen, rather than refresh as it does in TUI.

The fact that we see "tui disable" is the TERM=3Dansi version of PR30523.

But even if we fix that, there's still no clear sign that we left TUI.

I think we should clear all windows, except the cmd window.
